Guide to Cloud Migration: Prerequisites, Types and Checklist

Prerequisites of Cloud Migration

Companies typically migrate their operations to the cloud in one in all three ways: a) from their first local data center to cloud computing platforms; b) from one cloud to a different cloud; and c) by performing reverse cloud migration, also referred to as de-clouding.

Before moving your data or application to the cloud, you ought to give some thought to the subsequent considerations:

• Make preparations within your application for the moving of information to the cloud. Applications that haven’t been adequately prepared cause problems during cloud migration.
• Determine what quantity moving will set you back. If they’re not carefully planned, most of those processes have the potential to end in unnecessary waste.
• Determine your preferences within the cloud to support the wants of your company.
• To effectively manage your cloud database, you’ll require personnel with acceptable skills. Confirm that your data stored within the cloud is as safe as it will be.
• There is no simple solution. Always be able to accept the challenges that will arise during the migration of the appliance or data.
• Have a solid plan for moving your operations to the cloud. Create an idea that may make the transition as flexible and straightforward as possible, taking into consideration the requirements of your company.

Types of Cloud Migration:

SaaS (Software as a Service)

• It is the layer that’s the very top.
• Services for firms that are more flexible and are based online
• Rent on a monthly basis or services supported by the number of users
• Need substantial amounts of individualization within the service
• It requires support from the seller.
• It does so by constructing the elemental framework within the cloud with add-ons and supplementary components.
• When everything is prepared to travel, the service is moved from the local or shared hosting to the SaaS cloud. This transition takes place once everything has been properly founded.
• The whole process is jerky into several stages.
• The customer is required to own licenses so as to use them.
• Some samples of software as a service include Gmail, Google Docs, and Adobe Photoshop.
• It is the migration method that has rock bottom overall cost.

IaaS (Infrastructure as a Service)

• It is the idea upon which cloud computing is made.
• It encompasses the services of knowledge backup, data storage, and data security.
• Databases, space for storing, private virtual servers, and various other support services are made available on-demand through the online service.
• They charge the customer supported the quantity of information that they use or the quantity of your time that they use it.
• The transfer of knowledge or applications from an area or shared hosting server to a server that’s dedicated to the cloud
• It is a difficult process that’s allotted by developers.
• The complexity arises from the interdependencies of the information and therefore the functionality of the appliance.
• Cloud Migration could be a process that takes time.
• It is anticipated that both the information and also the application will still operate normally after the migration to the new IaaS server.
• It encompasses services additionally as physical resources like storage devices, computing servers, and network nodes.
• You can either purchase it upfront or on a usage-based subscription basis.
• One provider of this sort of service is thought as Amazon Web Service (AWS), and that they offer cloud computing as an example.

PaaS (Platform as a Service)

• The platform forms the core of the cloud’s middle layer.
• The infrastructure is beyond anyone’s ability to manage.
• Access is merely available through the application that has been deployed.
• It delivers the runtime whenever it’s required.
• It can function as either development or test environment, and it features a virtual machine that’s pre-installed with the software system, required middleware, and other necessary components. It is made available in step with the specifications of the project.
• The vendors supply the complete framework also because of the fundamental functions.
• The user is ready to develop their own applications within the confines of this environment.
• Microsoft Azure and Force.com, which is obtainable by Salesforce, are two samples of service providers that supply PaaS.
• Because it had been designed to be simple and easy, the method isn’t difficult.
• The process of moving to the cloud is often managed by anyone, no matter their level of technical expertise.
• The computer program and portal that are supported by browsers make it very easy to try and do.
• The portal makes the migration easier to accomplish.
• If the personnel involved have only a moderate or low level of technical expertise, you ought to anticipate some difficulties during the migration.

A Cloud Migration Checklist with 7 Items to Confirm a Successful Transfer

The question for businesses that have an interest in undergoing a digital transformation isn’t whether or when to adopt cloud computing and migrate their businesses upwards; rather, the question is when. If you would like your applications and data to be stored within the cloud as smoothly as possible, you ought to use cloud solutions that are tailored to your specific requirements. This may make sure that the migration process pops without a hitch. Once you’ve got migrated to the cloud, you would like to form sure that you simply are taking advantage of as many of the cloud migration benefits as you most likely can so you’ll be able to get the foremost value out of the transition. Once you are planning a smooth migration to your new cloud, here are seven points to contemplate as you create your plans.

1. How deep or shallow is it? Determine the “level” of cloud integration that’s appropriate for your specific requirements.

When you want to maneuver an application from an information center that’s located on-premise to the cloud, you’ve got two options: you’ll be able to either use shallow cloud integration or deep cloud integration. Both of those options are described in additional detail below. Within the first method, which is additionally called “shift-and-lift integration,” the on-premise application is moved to the cloud while the servers themselves undergo either no or only minimal changes. You simply must make some tweaks to the application itself so as for it to function properly within the new environment. During the “deep cloud integration” process, your application is modified while it’s being moved to the cloud so as to require the advantage of assorted key cloud capabilities.

2. Single cloud or Multi-Cloud?

When compared to using multiple clouds, it’s simpler to optimize your application to figure with one cloud because your development team will only become at home with one set of cloud APIs. In the event that you simply ultimately attempt to go together with a special provider, you will, however, be required to start the migration process everywhere again from scratch. After you have multiple applications or parts of the identical application that, if run on different clouds, would give increased business leverage, the multi-cloud approach may be useful. This can be very true in situations where you have got multiple applications. Engage the services of a knowledgeable cloud solutions provider, like unique solutions, who are able to direct you through the subsequent best step within the process. (Not relevant).

3. Establish a baseline for your performance

The process of measuring the performance of your application before migration so as to work out the amount of performance that is acceptable after the migration is noted because of the “baselining” process. The method of building baselines will assist you in determining when your migration has been successfully completed and can provide validation of the post-migration performance improvements you anticipated. During the method of migrating to the cloud, you’ll be able to also visit baselines to diagnose any problems which will occur.

4. Determine the order of the migration supported by the priority

When you migrate, you have got the choice of migrating your entire application directly, migrating components one at a time, or migrating services one at a time. You furthermore may have the selection to migrate the appliance in its entirety. You may start the migration process with the services that have the fewest dependencies, like your most internal services, so proceed to your outermost services, which are those that are closest to your customers. This could make the task significantly easier.

5. Should we move the info or should we keep it?

It is possible that the performance of your applications will suffer significantly if you progress only your data to the cloud while keeping the data-access methods primarily on-premises. If, on the opposite hand, the info remains stored on-premise, but the service that accesses it’s hosted within the cloud, this presents its own set of challenges. As a result, moving data from one location to a different will be a challenging Endeavour. During this case, it’s in your best interest to hunt for the help of a third-party cloud migration service provider who can provide their objective point of view so as to attain the required result.

6. So as to make sure of coherent transfer, your application should undergo any refactoring that will be necessary.

Before your application and services will be migrated, there’s a chance that they’re going to require some refactoring so as to continue functioning in a good and efficient manner. It’s possible that the explanations have something to try with a provision to permit dynamic scaling, the power to allocate and de-allocate resources as required, and a greater target service.
