What is PaaS in Cloud Computing?

PaaS stands for Platform-as-a-Service, a ready-to-use platform that keeps the architectural structures behind the scenes so that the programmers can focus solely on coding. It enables the developers to keep their attention on the coding aspect without spending time on the infrastructure needed to develop and launch apps. The service is similar to FaaS, which is function-as-a-service. The PaaS service allows the developers to use their servers’ hardware and software, which frees up the developers’ time. In addition to this, many organizations view this as a good option which enables them to operate cost-effectively. 

What does PaaS provide?

PaaS will not transform the existing IT infrastructure of a company for developing the software. It is supplied with the hosted infrastructure of a cloud service provider. Developers often use a web browser to access the services. To provide solutions like hosting an application and Java development, PaaS can be delivered through public, private and hybrid clouds. This includes other PaaS services:

  • Coordination of development teams
  • Development of applications
  • Evaluating and implementation of applications
  • Integration of Web Services
  • Safety of information
  • Integration of the database

The main advantage of PaaS is user-friendliness and convenience. A large number of infrastructure and other IT services are provided by the PaaS provider, which users can access through any web browser. The pay-per-use option allows companies to reduce their operating costs for hardware and software at the premises.

Advantages and Disadvantages of PaaS

Accessibility of service or consistency may be an issue for PaaS. If a provider suffers a service breakdown or other infrastructure breakdown, this can negatively affect clients and lead to expensive productivity deficiencies. Even so, PaaS providers are reasonably busy. There is also a possible issue with organizational change to a PaaS product. For instance, if a PaaS provider does not support the current programming language or chooses to use another set of design tools, it can have disruptive effects on users. 

To know the implication of the provider’s plan on their environment and capacity, customers must adopt the PaaS service provider’s blueprint. Lock-in vendors are another significant issue since many of the knowledge and programs from one PaaS product to another competing product cannot easily migrate. When selecting a PaaS provider, users must assess the corporate risks of service downtime and vendor lock-in.

PaaS products are aimed at the development of software. The platforms provide computer and storage facilities and text editing, versioning, compilation and evaluating services that allow developers to efficiently and decisively develop new software. A PaaS item also allows project managers, irrespective of geographical position, to cooperate and work together.

PaaS architectures hide from developers and other users their underlying infrastructure. This means that the cloud provider handles and operates the server and controls the distribution of resources, which is similar to the serverless computer and function-as-a-services architecture. 

Types of PaaS

The different types of PaaS, are as follows:

  • PaaS Public
  • PaaS Private
  • PaaS Hybrid
  • PaaS Communications
  • PaaS Mobile
  • OpenPaas Open

The most suitable and viable option for developers is Public, as it has enabled them to public cloud applications. Public PaaS allows users to control the deployment of software, while the cloud provider manages the delivery of all other major IT components required for hosting applications, including hardware and software, databases, servers and networks of storage systems.

Public PaaS retailers offer middleware that increases the scope, without the need for infrastructure setup, configuration and control of database servers. PaaS consists of several main processes for cloud infrastructure such as servers, networking systems, hardware and software, storage services, micro-ware, and databases. The PaaS service provider owns, sets up, and manages all of these various technologies.

These managed solutions reduce the client’s administrative burden of IT and provides customers with an attractive financial argument. This is mostly a good option if the developers cannot invest in these essential IT elements to not use them to the most significant degree. PaaS also offers tools like development tools, languages for programming, libraries, database management systems and other such devices that are needed to operate the cloud systems. 

Since PaaS is a cloud-based service, it has many risks involved such as security threats. PaaS is built on the notion of using common resources like networks and servers. Therefore, security risks include installing sensitive data in this setting and stolen data from hackers or other wrong actors because of unauthorized access and attacks. However, the leading cloud services have been better able to prevent such violations than the typical data center. The risk of information security is not what many in IT loathed at first.

AWS Migration in 5 Easy Steps

What is AWS?

AWS stands for Amazon Web Services and is a cloud-based solution that is provided by Amazon. AWS is currently being used by millions of customers, businesses, and government agencies. In addition to this, it has 175 web services with data centers across the globe. Furthermore, AWS is scalable, customizable, and innovative.

What is AWS Migration?

In essence, AWS migration is the transferring of data from one cloud service to Amazon, or it could also be the transfer of data from on-premises to the cloud. A lot of data that businesses generate every day and store on-premises is a costly and ineffective process, so transferring the data to the cloud is a much safer and reliable measure since AWS gives you tools to take care of the data, including AWS auto-scaling.

Why should we migrate to AWS?

As per the recent stats, it is predicted that more than 1/3rd of the data would go through the cloud by 2020. Keeping this in mind, there are other reasons as to why you should seriously consider migrating to AWS, such as:

  1. Update your current IT base
  2. Equipt yourself for the future
  3. Minimal setting up costs
  4. Security
  5. Ramp up the business agility
  6. Your website is now getting heavy traffic
  7. Recover data in case of loss

How do we migrate to AWS?

Well, if it is an on-premises server that you used to store the data, then you can migrate your data to AWS using the following steps:

Step 1

Opportunity & Evaluation

It is well documented that 70% of IT projects cannot succeed, and an additional 60% of dev-ops are unable to achieve or bring nothing to the table. The problem can be rooted back to a lack of understanding in the planning process. It would help if you kept in mind numerous core things when you consider migrating, such as your property, the apps, the data, motivations, stakeholders’ goals, and the budget. One of the first things that you need to keep in mind is the Business Architecture Overview; to develop this, the following items need to be done:

  1. Understand the business requirements.
  2. The vision
  3. Stakeholder buy-in
  4. ROI and business plan

Step 2

Portfolio and Planning

In this step, you need to inspect configuration management databases (CMDBs) and tools like AWS Discovery Service or RISC Networks to understand better what’s in the environment. Once you have this knowledge, you can create a strategy to approach critical phases of migrations, i.e., Application and Data Migration.

  1. The licensing process is a complex one, and you need to keep this in mind with AWS migration.
  2. In case you operate a large mainframe, you might need to integrate them accordingly with an SOA/Cloud-Native Application, which will create a hybrid architecture.       
  3. If any of your apps are dependent on one another, then you may need to create a strategy to move them to the cloud without disrupting the order in which they are dependent.

Step 3 & 4

Designing, Migrating & Validating Applications

When migrating, you need to move the least complex app, learn the target platform as you relocate, and then slowly migrate all of your more complex apps onto the system. In addition to this, the team’s Cloud Centers of Excellence help the companies to migrate more effectively without running into any problematic issues. As you move towards the AWS servers, you need to test and decommission the old system simultaneously. These two systems need to be run parallel to ensure that everything is being tested in real-time.

Step 5

Modern Operating Model 

The best strategy to optimize AWS is to automate everything. In addition to this, DevOps is also a practical path that businesses can take to achieve this. Once you have done this, you need to go back to the ROI and the business plan to ensure that the stakeholders are satisfied. The end-users are happy that management changes have taken place to facilitate the shift of the DevOps-centric structure. Lastly, it would be best to evaluate whether you are using the AWS foundation architecture to transform the business because the business plan’s transformation is the primary goal of shifting to AWS.
