Azure Migration Methods

Internet hosting on the cloud is a well-liked selection in the present day. Quite a lot of functions which can be being developed are hosted on the cloud in order to leverage the trendy internet hosting capabilities it presents. No upfront price is required for purchasing and sustaining Infrastructure. This feature is affordable. You simply pay for what you employ. And the infrastructure may be commissioned in minutes and may be disposed of anytime when it’s now not  wanted.

Due to the options supplied by cloud internet hosting, a whole lot of present functions are being migrated to the cloud as nicely. Nevertheless this isn’t that straightforward. The technique needs to be deliberate very rigorously and executed easily for issues to go nicely submit migration.

Azure has an edge over others on the earth of cloud computing due to the wide selection of companies it offers and its ease of use. It’s a extremely secured surroundings and is compliant with trade and authorities requirements across the globe. Based mostly on the larger diploma of flexibility it presents and ease of adoption, a number of functions are being migrated to Azure.

Right here on this article we’ll talk about the main methods that should be adopted whereas migrating an utility to the Azure cloud.

Cloud Agnostic or Cloud Native on Azure


Whereas deciding the technique it’s critical to resolve whether or not you must take the Cloud Agnostic route or a Cloud Native route.


It’s good to be cloud agnostic. A Cloud Agnostic strategy presents the applying not simply the power to shift from on premises to a specific cloud but in addition presents the aptitude emigrate throughout cloud distributors. It is a price efficient strategy and presents the aptitude to exit from a cloud service supplier any time and transfer to a brand new one. There isn’t any dependency of the applying with the cloud vendor. It’s free to be migrated to a different cloud vendor as-is with none code change. Right here the applying is optimized to take a seat on the cloud.


Nevertheless there are lot of fine choices particular to a cloud vendor that the applying wish to leverage. If the applying leverages something particular to a specific cloud vendor then it will get hosted as a cloud native resolution. The applying builds a decent dependency with the cloud service supplier by consuming a service particular to it. Nevertheless it’s good to be cloud native at occasions in order to eat the perfect providing, being supplied solely by a selected cloud supplier.



Whereas migrating functions to the cloud, the functions are tweaked a bit or some minor modifications are integrated in order that they’re optimized to run on the cloud. As soon as the functions are cloud optimized and are migrated then the troublesome a part of the migration journey is achieved and they are often additional enhanced to undertake all of the cloud advantages. A cloud agnostic strategy must be saved in thoughts whereas making the applying cloud optimized. Cloud native options require rebuilding from scratch and therefore must be prevented whereas taking a cloud optimized path. The cloud optimized path is the quickest and most economical method to transfer the applying to the cloud.


Based mostly on the choice of whether or not to be cloud optimized or cloud native, the following set of decisions may be made as a way to undertake the precise technique.


Cloud Optimized Methods for Azure Migration


In relation to migrating functions utilizing cloud optimized methods then there are three approaches out there:

  1. Rehost
  2. Refactor
  3. Rearchitect

Allow us to talk about every of those methods intimately.




A Rehost technique may be adopted everytime you simply have to host the prevailing utility to Azure with minimal efforts. No code change is required right here and the applying is migrated as-is. Normally such an possibility is an Infrastructure as a Service strategy and is an ideal instance of the Elevate and Shift technique. The migration is fast as no further code change is required right here. This route is taken every time there’s a talent hole wanted to boost the applying to make it cloud prepared or the applying has to get into the cloud Infrastructure from present datacenter shortly pertaining to a strict deadline.


This technique is often taken when the corporate wants to dump present On-Premises servers and transfer the applying to the cloud as an Infrastructure as a Service resolution. Right here the corporate will get  larger management on cloud Infrastructure for the hosted utility. Normally a digital machine is commissioned for this and the applying is moved from native IIS or another net host to the IIS or an online host on the Digital Machine. The identical type of surroundings as in on-premises is replicated on the Azure Digital Machine and the applying is configured and hosted as-is on the Digital Machine because it was hosted on the on-premises server. If the database getting used on-premises is a SQL Server then it is suggested to make use of Azure SQL Database Managed Cases. Another databases not out there by default on Azure Infrastructure must be put in and configured on a Digital Machine.

A Refactor technique is adopted every time there’s a want to suit the applying to the cloud with little or not many modifications made. The applying right here must be at minimal able to be hosted as a pure cloud utility. All mandatory modifications to make the applying cloud prepared are made. Normally such functions are hosted as Platform as a Service resolution. Normally the applying is modified as wanted in order that it may be hosted on Azure App Service becoming into the one of many internet hosting plans. The On-Premises utility is modified to make it cloud moveable.


If SQL server database is used then Azure SQL Database Managed Occasion can be utilized, else the database may be configured on an Azure Digital Machine.


There may also be a case the place there are portability points whereas adopting the Rehost technique. In such a case minimal modifications may be made to the applying and may be hosted as Infrastructure as a Service resolution as nicely.


The essential concept right here is to include minimal modifications in order to have the ability to repackage the applying and port it easily to the cloud.

The cloud is rather more than a internet hosting surroundings. It presents fundamental traits like Availability, Reliability, Fault Tolerance and rather more. With Refactor and Rehost choices it is possible for you to to leverage the cloud advantages at a minimal. Nevertheless to unleash the cloud goodness to the utmost extent, the applying needs to be modified at structure degree in order that it will possibly match into the cloud companies like Azure Kubernetes Providers or Azure Service Cloth. In such circumstances a Rearchitect technique is adopted.

With present or barely extra investments within the utility, all cloud benefits like scalability, reliability, and availability can be found on this possibility. Fashionable DevOps practices may be adopted with ease. Quite a lot of good Azure Providers can be utilized in such an strategy. Your entire migration is saved price efficient.

Cloud Native Methods for Azure Migration


In relation to migrating utility utilizing Cloud Native Methods then there’s one strategy out there.

Allow us to talk about this technique intimately.




On this strategy the applying is constructed once more from scratch. The principle aim right here is to make use of the Cloud Native options supplied by the Cloud supplier to the utmost extent. And on the similar time this strategy takes time as the applying is rebuilt and entails funding as lot of proof of idea needs to be labored on to see what all cloud native options must be adopted.


The applying may be moved to fashionable Serverless companies like Azure Logic Apps, Azure Occasion Grid, Azure Capabilities or many extra. Azure Cosmos DB can be utilized as Database resolution. This needs to be a Platform as a Service or a Serverless strategy. New age functions like Synthetic Intelligence, Blockchain, or Web of Issues functions may be constructed utilizing Azure particular choices in these areas. DevOps course of is rather more mature and easy right here as issues gel up completely with the cloud service supplier.

The choice tree is demonstrated within the under determine.


Azure Migration Strategies


Probably the most essential factor is from the place to start out and learn how to strategy. On this article we explored all the mandatory steps on this regard. Migrating from on-premise to the cloud is cool and is the necessity of the hour, however on the similar time it must be correctly deliberate and executed in a easy style in order to not get submit migration surprises. It’s at all times advisable to get into the cloud first utilizing a cloud optimized strategy after which usher in all cloud options as soon as the applying is within the cloud. To sum up, shifting to the cloud is a wiser selection than simply being caught with on-premises servers;  so that you may be within the fashionable age,  having fun with  all cloud options like Scalability, Reliability, Fault Tolerance and lots of extra.
