AWS Migration

Today when somebody is considering an option of the migration to cloud, AWS is definitely one of the main variants to think about. Though AWS migration is amazingly popular today, before making a decision to turn to it or not, you need to analyze all the peculiarities of this solution. And we are here to help you to deal with it.

Amazon AWS: What is it?

AWS (Amazon Web Services) is a cloud platform that offers a wide range of services including computing, data storing, and content delivery among others. All the opportunities offered are aimed at scaling and growth of businesses. The platform is known for the highest level of security provided.

To put it as simple as possible, let say that with AWS you can:

  • run your web and app servers in the cloud;
  • store your data on the cloud which makes them available for you regardless of where you are at the moment;
  • easily and quickly share your data and files with the help of the Content Delivery Network;
  • store information using the most efficient databases like MySQL, PostgreSQL, Oracle and SQL Server.

And of course, it is not a full list of everything that the cloud can provide you with. In total, AWS can offer nearly 200 services.

The offerings of AWS include:

  • infrastructure as a service (IaaS),
  • platform as a service (PaaS),
  • packaged software as a service (SaaS).

Advantages and disadvantages of AWS migration

At the current moment, AWS is the most popular cloud platform. Businesses of all sizes and from all industries rely on it. And it is not a surprise for those who know the benefits of this cloud.

Among the pluses we should mention:

  • easiness in use;
  • absence of any capacity limits;
  • fast deployment;
  • security and reliability.

However, there are some issues that may make AWS not the universal solution for migration to cloud. They are:

  • limits on resources (images, volumes, and snapshots) on Amazon EC2 and Amazon VPC console, the limits differ in different regions;
  • fees for technical support.

If we compare Amazon AWS with Microsoft Azure and Google Cloud, we will see that AWS has the biggest number of the zones where it is available, as well as the biggest market share and number of services provided.

However, the most important weak point of the platform that may become an obstacle for some businesses to opt for AWS migration is cost. In comparison with other platforms, AWS has the highest prices.

AWS migration strategies

If you want to migrate your data to AWS, you should know that there are several strategies for you.

We recommend you to consider the following 6 options:

  • Rehosting (you may have heard about it as a “lift-and-shift” strategy). The code is not re-written before the migration, apps are just “sent” to the cloud in this very case. However, quite often later they need to be optimized.
  • Replatforming. The core architecture of the app is not changed.But it may be optimized before the migration to a Database-as-a-Service platform as Amazon RDS for example or to a fully managed platform such as Amazon Elastic Beanstalk.
  • Repurchasing. In fact, you move to a different product (quite often to a SaaS platform).
  • Re-architecting. In such a case the architecture is usually updated with cloud-native features.
  • Retire. If you see that some of your applications are no longer useful, you can just get rid of them, which will help you to save your money (for both further migration, if needed, and maintenance).
  • Retain. This approach presupposes just leaving everything without changes at least for some time. If you still haven’t prioritized some of your apps for migration, it’s better not to migrate them right now. After you get a clearer understanding which applications you need to have in the cloud, there will be no reasons to retain them further.
