If you own a business, deciding between a cloud server and a dedicated server hosting solution is a critical decision. Many businesses used to start on a shared Linux server when they first learned about web hosting, and then they upgraded to dedicated servers to handle the increased web traffic.

Today, cloud hosting is the new paradigm, and businesses are no longer required to follow this traditional path, but can instead begin building a website on a managed cloud plan. Previously, it would have taken more time for the developer to build on a dedicated server independently, but thanks to new technology, this is no longer the case.

What is cloud hosting?

Cloud hosting is a method of hosting websites that distributes data across multiple machines. Users can manage their data that access the various servers in the cloud by using virtual machines. A significant difference between a cloud server and a dedicated server is that cloud hosting uses the computing power and services of multiple machines.

How does cloud hosting work?

When comparing a cloud server to a dedicated server, it is necessary to first understand how cloud servers work. Airzero Cloud, the best cloud hosting service, uses a virtual server that uses cloud computing technology to distribute data among connected servers located in different areas.
It is critical to understand the distinctions between public, private, hybrid, and managed cloud hosting frameworks when it comes to web hosting. You should also understand how these services relate to the specific web hosting requirements of Kerala's small businesses and other start-up software companies. Even business website owners must be aware of the distinctions between software as a service, platform as a service, and infrastructure as a service plan.

Advantages of cloud hosting

When it comes to cloud hosting, there are numerous plans, platforms, and services to choose from. These are exclusive to the company and the programming team that created them for the market. One of the primary benefits of cloud hosting plans is that they include a preinstalled elastic web server that supports custom stack software. This hosting provides more RAM and CPU cores, allowing each site to scale to consume more resources as needed.

What is dedicated server hosting?

On a physical server, this hosting could support a single client. A single client may require a cluster of servers, which is referred to as a private cloud. This is based on virtual technology, with many dedicated servers contributing to the virtual location. Only resources in the virtual space will be delivered to the client.

How does dedicated server hosting work?

The traditional benefit of such servers is that system administrators can easily configure them for the precise level of web traffic required to support online operations. Website owners will also need to provision dedicated servers with excess capacity, which will provide better performance during periods of lower-than-peak traffic activity.

Advantages of dedicated server hosting

When it comes to dedicated servers, the key advantage is customization. Most Kerala businesses must handle a high volume of traffic or run complex applications on a regular basis. Dedicated server hardware is required by web developers and programmers in order to create custom web server environments for complex application support. To build new applications or support legacy software, most developers will require dedicated server hardware that can be fully customized. The dedicated servers can be easily optimized to support high levels of web traffic for media, publishing, promotions, and other purposes.

Choosing the right server for your business

Dedicated servers were the traditional way to go, but cloud computing options are becoming increasingly competitive alternatives for developing small business software solutions at a low cost. All of this adds to the complexity of the cloud server vs. dedicated server debate.

You can also use a hybrid cloud, which may be a viable solution because it combines the benefits of both cloud and dedicated hosting.

It is up to you to select the best server. There is nothing wrong with either dedicated server hosting or cloud hosting because each has advantages. With all of the points mentioned above, you must select the one that best suits your company's needs. So, with all of this in mind, make sure you select the right server for your company.

A security group controls inbound and outbound traffic for your EC2 instances by acting as a virtual firewall. When you launch an EC2 instance in a VPC, you can assign the instance up to five security groups. Security groups operate at the instance level rather than the subnet level. As a result, each instance in a VPC subnet can be assigned to a different set of security groups.

If you launch an instance using the Amazon EC2 API or a command-line tool without specifying a security group, the instance is assigned to the VPC's default security group. When you launch an instance through the Amazon EC2 console, you can create a new security group for the instance.

You add rules to each security group that controls inbound traffic to instances and a separate set of rules that control outbound traffic. This section explains the fundamentals of security groups and their rules for your VPC.

Set up network ACLs with rules similar to your security groups to add an extra layer of security to your VPC. See Compare security groups and network ACLs for more information on the distinctions between the two types of ACLs.

Security group basics

Security groups have the following characteristics:

  • Allow rules can be specified, but not deny rules.
  • You can define different rules for inbound and outbound traffic.
  • You can use security group rules to filter traffic based on protocols and port numbers.
  • Security groups are stateful,which means that if you send a request from your instance, response traffic for that request is allowed to enter regardless of inbound security group rules. Regardless of outbound rules, responses to allowed inbound traffic are allowed to flow out.
  • When you create a security group for the first time, it has no inbound rules. As a result, until you add inbound rules to the security group, no inbound traffic from another host to your instance is allowed.
  • A security group includes an outbound rule by default that allows all outbound traffic. You can remove the rule and replace it with outbound rules that allow only specific outbound traffic. If your security group does not have any outbound rules, no outbound traffic from your instance is permitted.
  • There are limits to how many security groups you can create per VPC, how many rules you can add to each security group, and how many security groups you can associate with a network interface.
  • Instances in a security group cannot communicate with one another unless you add rules allowing the traffic (exception: the default security group has these rules by default).
  • Network interfaces are linked to security groups. You can change the security groups associated with an instance after it has been launched, which changes the security groups associated with the primary network interface (eth0). Any other network interface's security groups can also be specified or changed. When you create a network interface, it is automatically assigned to the VPC's default security group, unless you specify a different security group. See Elastic network interfaces for more information on network interfaces.
  • A security group can only be used within the VPC that you specify when you create it.

Your VPC's default security group

Your VPC comes with a default security group. If you do not specify a different security group when you launch the instance, we use the default security group.

You can modify the default security group's rules.

A default security group cannot be deleted. When you attempt to delete the default security group, you will receive the following error:

 Client.CannotDelete: the specified group: "sg-51530134" name: "default" cannot be deleted by a user.

We do not automatically add an outbound rule for IPv6 traffic when you associate an IPv6 block with your VPC if you have modified the outbound rules for your security group.

Security group rules

A security group's rules can be added or removed (also referred to as authorizing or revoking inbound or outbound access). A rule can be applied to either inbound or outbound traffic (egress). You can grant access to a specific CIDR range, another security group in your VPC, or another VPC in a peer VPC (requires a VPC peering connection).

A security group's rules govern the inbound traffic allowed to reach the instances associated with the security group. The rules also govern the amount of outbound traffic that is permitted to leave them.

Security group rules have the following characteristics:

  • Security groups are configured to allow all outbound traffic by default.
  • Security group rules are always permissive; rules that deny access cannot be created.
  • You can use security group rules to filter traffic based on protocols and port numbers.
  • Security groups are stateful, which means that if you send a request from your instance, the response traffic is allowed to flow in regardless of the inbound rules. This also implies that responses to permitted inbound traffic are permitted to flow out, regardless of the outbound rules.

For each rule, you specify the following:

  • Name :he security group's name. A name can have up to 255 characters. Characters allowed are a-z, A-Z, 0-9, spaces, and. -:/()#,@[]+=;!$*. When we save a name that contains trailing spaces, we trim the spaces. For instance, if you enter "Test Security Group" as the name, we will save it as "Test Security Group."
  • Protocol: The protocol to allow. The most common protocols are 6, 17, and 1.
  • Port range:The range of ports to allow for TCP, UDP, or a custom protocol. You have the option of specifying a single port number or a range of port numbers.
  • Source or destination:The origin or destination of the traffic.
  • The current security organization
  • For the same VPC, a different security group
  • In a VPC peering connection, a different security group is assigned to a peer VPC.

When you create a security group rule, AWS assigns the rule a unique ID. When you use the API or CLI to modify or delete a rule, you can use its ID.

When you specify a security group as the source or destination of a rule, the rule applies to all instances associated with that security group.

When you specify a security group as the source for a rule, traffic from network interfaces associated with the source security group is allowed for the specified protocol and port. Incoming traffic is permitted based on the private IP addresses of network interfaces linked to the source security group. If you configure routers to forward traffic between two instances in different subnets via a middlebox appliance, you must ensure that both instances' security groups allow traffic to flow between them.

Some firewall configuration systems allow you to filter on source ports. You can use security groups to filter only on destination ports.

When you add, update, or delete rules, the changes are applied to all instances associated with the security group.

The type of rules you add is frequently determined by the purpose of the security group. The table below contains example rules for a security group associated with web servers. The web servers can accept HTTP and HTTPS traffic from any IPv4 or IPv6 address and send SQL or MySQL traffic to a database server.

A different set of rules is required for a database server. Instead of inbound HTTP and HTTPS traffic, for example, you could add a rule that allows inbound MySQL or Microsoft SQL Server access.

Stale security group rules

If your VPC has a VPC peering connection to another VPC or uses a VPC shared by another account. This enables instances belonging to the referenced security group and those belonging to the referencing security group to communicate with one another.

The security group rule is marked as stale if the security group in the shared VPC is deleted or if the VPC peering connection is deleted. Stale security group rules can be deleted just like any other security group rule.

Work with security groups

Change the default security group.

A default security group is included in your VPC. This group cannot be deleted; however, the rules of the group can be changed. The procedure is the same as for any other security group modification.

Make a security group.

Although the default security group can be used for your instances, you may want to create your own groups to reflect the various roles that instances play in your system.

New security groups are created with only an outbound rule, which allows all traffic to leave the instances.

  • To start the Amazon VPC console.
  • Select Security Groups from the navigation pane.
  • There is a list of your security groups. Select the security group to view the details for that security group, including its inbound and outbound rules.
  • able any inbound traffic or to restrict outbound traffic, you must add rules.

  • The protocol and port range are automatically configured for any other type.

b. To allow traffic, do one of the following for the Source (inbound rules) or Destination (outbound rules):

  • Select Custom and then enter a CIDR-encoded IP address, a CIDR block, another security group, or a prefix list.
  • Select Anywhere to allow traffic from any IP address to reach your instances (inbound rules) or All IP addresses to allow traffic from your instances to reach all IP addresses (outbound rules). This option adds the IPv4 CIDR block automatically.
  • If your security group is in an IPv6-enabled VPC, this option adds a rule for the::/0 IPv6 CIDR block automatically.
  • This option is acceptable for inbound rules for a short period of time in a test environment but is unsafe for production environments. Only allow a specific IP address or range of IP addresses to access your instances in production.
  • Choose Save rules.

To add a rule using the command line

  • authorization-security-group-entry and authorization-security-group-egress

AWS Firewall Manager can be used to centrally manage VPC security groups.

AWS Firewall Manager streamlines the administration and maintenance of your VPC security groups across multiple accounts and resources. With Firewall Manager, you can configure and audit your organization's security groups from a single central administrator account. Firewall Manager applies the rules and protections to all of your accounts and resources automatically, even as you add new ones. Firewall Manager is especially useful if you want to protect your entire organization or if you frequently add new resources that need to be protected from a central administrator account.

  • Configure your organization's common baseline security groups as follows: A common security group policy can be used to provide centralized control over the association of security groups to accounts and resources across your organization. You specify where and how the policy will be implemented in your organization.
  • Audit existing security groups in your organization: An audit security group policy can be used to check the existing rules in your organization's security groups. The policy can be configured to audit all accounts, specific accounts, or resources tagged within your organization. Firewall Manager automatically detects and audits new accounts and resources. You can create audit rules to specify which security group rules to allow or disallow within your organization, as well as to look for unused or redundant security groups.
  • Obtain reports on non-compliant resources and correct them: For your baseline and audit policies, you can receive reports and alerts for non-compliant resources. You can also configure auto-remediation workflows to remediate any non-compliant resources detected by the Firewall Manager.

What is a RAID Controller?

A RAID controller is a hardware appliance or software schedule that manages hard disc drives or solid-state movements in a computer or storage array so that they can function as a logical unit. A RAID controller security stored data while also potentially enhancing computing commission by revving access to stored data.

  • A RAID controller acts as a bridge between an operating system and the physical drives.

A RAID controller offers applications and operating systems businesses or areas of drives as analytical units for which data security systems can be defined. Even though they may consist of parts of multiple drives, the logical units appear to applications and operating systems as endeavors. Because the controller can access numerous copies of data across numerous physical devices, it can improve performance and protect data in the event of a system crash.

There are approximately ten different RAID configurations unrestricted, as well as numerous proprietary variations of the standard set of RAID levels. A RAID controller will support a single RAID level or a group of levels that are related.

  • Hardware vs. software RAID controllers

A physical controller is used to manage the array in hardware-based RAID. The controller can be a PCI or PCI Express card that is created to support a specific drive format such as SATA or SCSI. Hardware RAID controllers are also known as RAID adapters.

Hardware controller prices vary significantly, with desktop-capable cards available for less than $50. More cosmopolitan hardware controllers capable of keeping shared networked storage are quite more expensive, typically ranging from a few hundred dollars to more than a thousand dollars.

LSI, Microsemi Adaptec, Intel, IBM, Dell, and Cisco are simply a few of the companies that currently provide hardware RAID controllers.

When choosing a hardware RAID controller, you should consider the following key features:

  • Interfaces for SATA and/or SAS (and related throughout speeds)
  • Supported RAID levels

  • Compatibility with operating systems

  • Supported device count

  • Performance in reading

  • IOPs evaluation

  • PCIe interface cache size

  • Capabilities for encryption

  • Consumption of energy

A controller can also be software-only, using the host system's hardware resources, especially the CPU and DRAM. Although software-based RAID delivers the same functionality as hardware-based RAID, its implementation is typically inferior to that of the hardware versions.

Because no special hardware is needed, the main benefits of using a software controller are flexibility and low cost. However, it is crucial to ensure that the host system's processor is powerful enough to run the software without negatively impacting the performance of other applications running on the host.

RAID controller software is contained in some operating systems. For example, RAID capabilities are provided by Windows Server's Storage Spaces facility. Most enterprise-class Linux servers include RAID controller software in the form of the Linux mdadm utility.

Third-party software RAID controllers, such as SnapRAID, Stablebit DrivePool, SoftRAID, and FlexRAID, are also available. These programs are typically adequate for small installations but may not meet the storage performance and capacity requirements of business environments.

Some commercially available storage arrays use software RAID controllers, but the software is typically developed and enhanced by the storage vendor to provide adequate performance. Furthermore, storage systems with software controllers are typically built around powerful processors dedicated to controlling and managing the shared storage system.

Airzero cloud is a cloud hosting service that provides compute power, database storage, content delivery, and a variety of other functions that aid in business integration.

If you have any doubt about the RAID controller. Don’t hesitate to contact us. Airzero cloud will be your digital partner.

What is Bitcoin?

Bitcoin is a decentralized digital currency that you can purchase, trade and exchange directly, without a mediator like a bank. Bitcoin’s founder, Satoshi Nakamoto, initially defined the demand for “an electronic payment system based on cryptographic evidence instead of trust.”

Each and every Bitcoin trade that’s ever been created lives on a public ledger available to everyone, making trades difficult to change and difficult to fraud. That’s the core plan: Core to their decentralized character, Bitcoins aren’t backed by the government or any issuing organization, and there’s nobody to ensure their value besides the evidence baked in the heart of the device.

Bitcoin Core gives you improved safety and solitude at a cost. You ought to take accountability for the safety of your bitcoins, meet higher minimum system needs, and beware of some possible requirements.

What is the wallet responsibility checklist?

Bitcoin Core makes you in charge of the wallet that you owned, which means your bitcoins are in danger unless you finish certain simple tasks:

  • Give a backup of your keys
  • Ensure your wallet is secure
  • Setup an offline wallet for certain amounts of bitcoins
  • Continuously look to your security notifications
  • Make your heirs receive your bitcoins if you passed away or become incapacitated

If you require help with any step, please enquire for assistance in any of Bitcoin’s friendly forums or live chatrooms

What are the system requirements?

Bare minimum with default settings requirements:

  • Disk space with 350 GB
  • Download 250MB/day
  • Upload 5GB/day
  • Memory(RAM) at least 512MB
  • Needed desktop or laptop
  • Operating system Linux, Mac, windows

Bare minimum with custom settings requirements:

  • Diskspace 7GB
  • Download 150MB/day
  • Upload 10MB/day
  • Memory 256MB
  • The system must be desktop, laptop with an ARM chipset.
  • Operating system Windows, Mac OSX, Linux, BSD

Minimum recommended requirements:

  • Disk space 350GB
  • Download 500MB/day
  • Upload 5GB/day
  • Memory 1 GB
  • System desktop, laptop
  • Operating system Windows, Mac Osx, Linux

What are the Possible Problems?

  • Legal: Bitcoin use is banned or limited in some areas.
  • Bandwidth limits: Some Internet programs will charge an extra amount for any extra upload bandwidth employed that isn’t contained in theplan. Worse, some providers may terminate your association without notification because of overuse. We recommend that you review whether your Internet association is subjected to such restrictions andmonitor your bandwidth use so that you can intercept Bitcoin Core before you advance your upload limit.
  • Anti-virus: Several individuals have positioned parts of known computer viruses in the Bitcoin blockchain. This blockchain data can’t contaminate your computer, but some anti-virus programs quarantine the information anyway, making it more challenging to run Bitcoin Core. This issue mostly involves computers running Windows.
  • Attack target: Bitcoin Core powers the Bitcoin peer-to-peer network, so people who like to disrupt the network may interrupt Bitcoin Core users in methods that will impact other things you do with your system, such as aggression that restrict your available download bandwidth.

If you have any doubts about bitcoin core requirements and warnings, Don’t hesitate to contact us through the below email. Airzero cloud will be your digital partner.

The nature of cryptocurrency is increasing by leaps and bounds every day. Unlike normal money that is written, these digital assets, including Bitcoin — the world's biggest and oldest cryptocurrency — are worked. It's the means of gaining a cryptocurrency by doing cryptographic comparisons using a huge computing arrangement, electricity, and valuable software. So, if you need to know more about cryptocurrency and Bitcoin mining, read on.

What is Bitcoin mining?

If you have only learned of purchasing or selling Bitcoins, the term ‘mining' may be a different one for you. But it is sure that you can get your personal Bitcoin if you have the needed machinery. The cryptocurrency is generated with the maintenance of a complex and very technical manner. Post mining, new Bitcoins are included for distribution. However, crypto mining is not just about building new coins. It also involves verifying the cryptocurrency transactions on the blockchain.

How to mine Bitcoins?

Mining Bitcoins is a difficult method due to its intricate nature. To perform it simply, let's take an example of valuable metals and the way they are worked. For gold and silver, the soul mining them removes them through mining. However, a person mining cryptocurrency will have to join new coins into circulation. For this, complex mathematical equations are required to be solved.

How does it work?

To mine Bitcoins and other cryptocurrencies, you'd require huge processing power. The higher the processing power of your computer, the higher will be the mining activity and interest. You want computers that have software specially created to resolve complex mathematical equations. Mining Bitcoins constantly needs an active internet connection.

To mine Bitcoins, you need a Graphics Processing Unit or Application-Specific Integrated Circuits. These are the two ways of mining cryptocurrencies. As far as the GPU process is involved, the computational power is built with many GPUs that run together. However, learning about ASICs, they can produce more coins as compared to GPU but they are very expensive.

What about Bitcoin mining pools?

If you cannot choose for your individual mining devices, you can go ahead and join a mining pool where your resources are clubbed with other people mining the coins. This will make sure to enhance processing power and improve results. This sounds greater and better, right? However, you have to distribute the final output because all the miners are involved in the mining pool. You wouldn't be enabled to earn the rewards solely as you could have done while mining personally.

Google has been fighting diligently to obtain the web safer and has now started to mark websites as “Non-Secure” which do not have an SSL certificate connected but still exchange user data. Therefore, it has now become a must to serve your website over HTTPS/SSL to ensure your visitors’ data and also to show that your name cares about safety. Coming to Chrome Push Notifications, although not a reservation, SSL is recommended for your main domain. There are a lot more advantages to joining an SSL certificate to your website including increasing your search rankings. In this post let’s dive deep into SSL certificates, their types and how you can set up a free SSL on your website.

What is an SSL certificate?

On most websites now, you will see that they start with “HTTPS://” in the URL with a green catch saying safe, that’s enough for the use of an SSL certificate. But that’s not just for indication, there is a lot going on behind the scene.SSL or Protected Sockets Layer helps build an encrypted link between your web server and the website visitor. This ensures that all data passed within the two is private and no one in the center has a way to it. Even if someone leads to tapping the attachment, the data will be of no advantage to them, as it is encrypted end-to-end. Getting back to the SSL certificate, it is a little file that connects a cryptographic key with your business and domain’s details. It is located on the server to allow HTTPS protocol and based on the kind of SSL certificate used, the Certificate Authority makes some checks on the organization’s knowledge. The browser and Operating system vendors run with these Certificate Authorities to embed the Root Certificates within their software so that the certificate can be confirmed and a reliable connection is placed between the web server and the end-user.

With an unsafe HTTP connection, third parties can snoop at the traffic passing among a web server and the browser to accumulate private data including email addresses, passwords as well as usernames. That is the purpose why Google, security experts are urging for the use of SSL on websites so that you get the rest of the mind that even the most essential data is protected from being intercepted.

Why do you need an SSL certificate on your website?

While eCommerce websites, banking companies have been using SSL for a very long time – small and medium enterprises, individual websites, blogs are starting to get back on plan now. Apart from the principal advantage of obtaining user knowledge and restriction of data leaks, one of the major driving factors has been Google’s webmaster guideline. It declares that SSL will be included as a ranking factor in their study algorithm. This was published and since then several websites have begun transitioning to HTTPS.So websites with an SSL certification are bound to get assistance in SERPs. Although it may not be a large ranking factor, it is definitely a positive signal. Moreover, lately, Google Chrome, the most extensively used browser on both desktop and mobile also began showing HTTP pages that collect passwords or credit cards as “Non-Secure”.

This would absolutely have an influence on your visitors who would think twice before typing any data on a website which the browser calls non-secure.

What are the different types of SSL certificates which one should you get?

Widely, there are three types of SSL certificates:

  • Extended Validation SSL Certificates
  • Organization Validation SSL Certificates
  • Domain Validation SSL Certificates

All three change in the guard and validation they offer along with cost. Since this blog is about a free SSL certificate.

What about the Extended Validation SSL Certificate?

These are assigned to organizations are the Certificate Authority confirms the particular right of the organization to use the detailed domain name along with the following: Physical, Operational Survival of the organization along with the legal license.

Authorization by the business for issuance of the EV SSL Certificate.

Organization Validation SSL Certificate

For an OV SSL Certificate, the CA will evaluate the right of your company to use the domain name. Some of the other analyses mentioned for EV SSL certificates may also be brought out. Your website visitants will be capable to see information about the organization.

Domain Validation SSL Certificate

This is the most fundamental form of an SSL certificate. Your license to use the domain name will be imposed. Users will be capable to see details about the encryption. Details about your companies are not shared.

How to secure your website with a free SSL certificate?

The simplest way to get a free SSL certificate is to sign up for Cloudflare.

  • First Create an account on Cloudflare

You want to add* and* independently, and for each of these URL patterns select ‘Always Use HTTPS’. One thing to note here is that this decision will only be available once the SSL certificate is issued.

The configuration will take a few minutes to go through. Once done, you can then open any page on your website, and it will open on HTTPS.
