There is a famous saying by Daniel Alarcon that says “How emigration is actually lived — well, this depends on many factors: education, economic station, language, where one lands, and what support network is in place at the site of arrival.
So, with this let us all check what is new today in this post and what is it emphasizing more on. This outline of the post is to share the strategies and process of migrating application to AWS cloud services. Hence, the details is all about six different migration strategies that needs to be considered and also that the customers implement it to migrate applications to the cloud.
These are the strategies that are built upon 5 R’s that is been outlined by Gartner her in 2011. This is indeed the final installation of three-parts series that are on migrations. Well, with this said to share the first post in this series is to introduce the concept of mass migration, which simply refers to as “migration” throughout the complete services. The second post describes the series of A process for mass migrations to the cloud. Also, one thing is that these posts stands on its own and this is also believed that they work together for a better way of result to come out.
Formulating a Migration Strategy
The typical way in which the enterprises begin to contemplate is to how to migrate an application during the second phase of the “migration process” – portfolio discovery and planning. This is only dine when they determine to understand what’s on their environment, its inter dependencies, what is going to be easy to migrate, and also what is that going to be hard to migrate, and how will they migrate each applications.
It is that with the technique of using this knowledge, the organizations can outline a plan and this can always be considered as a subject to change as they progress through their migration and learn. Another thing here is what considers is on how will they approach the migration on each of the application in their portfolio and also in what order.
Moving further, the complexity of migrating existing applications to another always varies. This is entirely depending on the team of architecture and existing licensing arrangements. If it was to think from the universe prospective, it would be all about the applications to migrate on a spectrum of complexity.
It would be that we here therefore suggest starting with something which is on low-complexity end of the spectrum for the reason which is obvious and that also it will be easier to get it complete. This will then give some of the immediate reinforcement or “quick wins” as you consider.
Further, now comes the actual part that needs to be understood her and that is the 6 R’s. This is called as the 6 application of Migration Strategies.
The 6 most common application migration strategies we see are:
- Rehosting — Otherwise known as “lift-and-shift.”
It is been found that there are many early cloud projects that are gravitating towards the net use of new development using cloud-native capabilities. But to this it is that in a large legacy migration scenario where the organization is looking to scale its migration quickly to meet a business case, we find that the majority of applications are re hosted. GE Oil & Gas, for instance, found that, even without implementing any cloud optimizations, it could save roughly 30 percent of its costs by re hosting.
The tool that is taken into consideration for rehosting the automated work with the toolsi s CloudEndure Migration, AWS VM Import/Export. It is also seen that although some customers prefer to do this manually as they learn how to apply their legacy systems to the new cloud platform.
We’ve also found that applications are easier to optimize/re-architect once they’re already running in the cloud. Partly because your organization will have developed better skills to do so, and partly because the hard part — migrating the application, data, and traffic — has already been done.
- Replatforming — I sometimes call this “lift-tinker-and-shift.”
Here we can or might consider taking few cloud optimizations in order to achieve some result-oriented and tangible benefits. But the core architecture of the application is not at all been getting changed here. This is also that you might be looking to have some sort of reduction in the amount of time that is been spent managing instances of the database and this is all possible by migrating to a database-as-a-service platform like Amazon Relational Database Service (Amazon RDS), or migrating your application to a fully managed platform like Amazon Elastic Beanstalk.
Also, it is that the large media companies are also working with the process where there are hundreds migrated web services that are running into on-premised of AWS and its process. It moved from WebLogic (a Java application container that requires an expensive license) to Apache Tomcat, an open-source equivalent. This media company saved millions in licensing costs on top of the savings and agility it gained by migrating to AWS.
- Repurchasing — Moving to a different product.
We here very commonly see repurchasing as a move to a SaaS platform. Moving a CRM to Salesforce.com, an HR system to Workday, a CMS to Drupal, and so on.
- Refactoring / Re-architect
The process of re-imagining how the application is being architect-ed and developed, the typical use of cloud-native feature is taken into consideration.
This is totally and typically been driven by a strong business need so as to add features, scale or performance which would otherwise be difficult to achieve in the application’s existing environment.
Also, it is that if you are planning to migrate from a monolithic architecture to a service-oriented or a server-less architecture, it requires to boost the quality and improve the business continuity.This pattern tends to be the most expensive, but, if you have a good product-market fit, it can also be the most beneficial.
- Retire — Get rid of.
It is that once the discovery of everything is being done in the environment, there may be a question to be asked to each functional area who owns each applications. It is that around 10% of the enterprises in IT portfolio is not at all useful and can easily be turned off.These savings can boost the business case, direct your team’s scarce attention to the things that people use, and lessen the surface area you have to secure.
- Retain — Usually this means “revisit” or do nothing (for now).
It may be that you are still thinking upon or riding out with some depreciation, and for the same it would be you are still not prepared or ready to prioritize an application that is recently been upgrade, or otherwise it would be not inclined to migrate some applications. It is that you should only migrate onto what makes sense for the business, and as the as the gravity of your portfolio changes from on-premises to the cloud, you’ll probably have fewer reasons to retain.
As a reader you may have got some of the information about the services of Cloud Migration Strategy. We at Cloud Stack Group have the team of well-trained engineers who have intensive knowledge of the work and which makes the entire process of work and project a easier way to get migrated from one server to another.
