The process of migrating applications to azure cloud comes has many circumstances, and it’s important to plan your work. Moving your infrastructure can be simple, but at the same time, re-architecting your application may be required to reap the benefits of IaaS and save money. In general, the code has to be rewritten again.
The process description
A preliminary analysis of the application is important for understanding if there are benefits or not. The point is that cloud service is not the cheapest solution. And if in a normal situation we rent a server, then in the cloud we spend resources. And reducing those costs, optimizing the application and using the right cloud solutions will get you great results to migrate to azure. The migration strategy is to gradually integrate the application into the cloud. One of its advantages is the ability to quickly try and get results. And at the same time, nothing prevents you from going back a step. The gradual adoption of cloud solutions will ultimately allow you to use the ones you really need. The most common solution is a hybrid infrastructure, when exactly those tools are used that carry great benefits and benefits.
Stage 1: Assess
The migration can be started only after evaluating the architecture of the application. The performance must be examined and also should be analyzed.
Stage 2: Migrate
New tools can be tried and tested reversibly with the help of cloud services. At any stage the user can go back. Up to the situation can be made correction, modification of the application, or abandoning of the implementation. For users now are available four approaches, presented in detail to let them make the right choice.
Stage 3: Optimize
When an application is already deployed and working, it should still be monitored. It’s done in order to look after the costs and make optimization.
Stage 4: Secure and Manage
With the help of security it is possible to understand the posture of the application. That would help to ensure that work of the application is carried out properly.
4 main strategies
Now let’s have a close look at strategies. They are created for moving an application to the cloud. Nowadays 4 of them are presented.
Refactor / Repackage
With the help of this solution the user can keep application code and logic. There are minimal changes. As for advantages of the cloud’s benefits, they all are accessible with microsoft azure consulting.
In fact, this option offers to remove from the application everything that can be taken in the cloud. Let’s say the application has Active Directory. Since the cloud has its own Azure Active Directory service, you do not need to transfer the usual one from the application, and you can use the cloud one. The same can be said about mail services, SharePoint, file sharing and many others, analogues of which are provided in the cloud.
Rehost / Lift and Shift
This option allows you to quickly deploy your application to the cloud. It is also known as “lift and shift”. The application is ported as it is, with no code changes.
Benefits: You can quickly migrate your application infrastructure and test it in the cloud.
To do this, you need to back up your servers using Azure Site Recovery as part of cloud migration strategy. You can copy both virtual machines and physical servers. The cloud includes tools for working with different databases. The Azure Database Migration Service tool will help you with this.
Rebuild
Having analyzed your application, we move on to the stage of connecting cloud services with DataArt company. Those parts of the infrastructure that can be replaced are processed into interfaces. This allows you to create a cloud infrastructure.
You can add cloud storage, cash, queues, and so on to the application. We get an Azure-style two-tier application, our web-application service.
You can gradually remove unnecessary things from it that do not provide services to users. Change backend to queues. Add storage – to receive all content through the Content Delivery Network. Connect redis cash so that requests are cached and the database does not twitch again. This is now a working application.
Rearchitect
The strategy is to optimize the application for the cloud service architecture. That being said, it is important to modify and extend it to take advantage of cloud scaling. This will improve performance and gain flexible scaling.
With this option, many applications are simply made into static sites. Because it is beneficial. The fee for storing this site in cloud storage is low, since html files take up a minimum of space. And the client pays only for traffic to his site and only for the occupied site space in storage.
The result is your cloud-enhanced application. Keeping your finger on the pulse of a cloud provider is beneficial. New instruments appear quite dynamically. Their architecture makes it relatively easy to experience, try, find out if it’s right for you.
