Is Migration to the Public Cloud (“Hyperscale”) Right for You?
Cloud this, cloud that. Everybody is talking about their cloud applications and migrating their company’s infrastructure to the public cloud. So, it’s logical to assume that you should also migrate all your apps to the cloud, right? That’s not always the case. Every circumstance, application, and organization is unique and it’s important to properly analyze your situation to make sure you are making the right choice.
In many cases, migration to the public cloud is a very attractive option; however, it’s imperative that you first assess whether it adds business value – through an assessment of all applications.
In addition to going all-in on public cloud, there are several other cloud deployment methods.
Where to Start When Determining if Cloud Migration is Right for You
It is imperative that you understand what you are trying to accomplish with your cloud migration. What is it that motivates you to complete this process? Is your company looking to scale quickly and establish a more agile infrastructure? A practical Q&A offers greater ability to pivot and increase flexibility with business processes and decisions.
If you jump into cloud migration too quickly, you can cause problems for yourself down the line that may cost your organization money and time. Before starting your migration, it’s important to have clear answers to questions surrounding your cloud migration.
Nail Down Your Motivation with These Questions:
Understanding your motivation for cloud migration is the most vital part in deciding on whether you want to migrate to the public cloud. But, finding the right questions to help further assess your need for cloud migration is the truly difficult part. To help, I’ve put together a short list of three key steps – and corresponding questions – you will want to address before finalizing your cloud migration decision:
1. Which Applications?
If you are unsure about your applications and if you should migrate them to the cloud, you’re in luck. There are services such as Amazon Web Services Application Discovery Service and the Azure Cloud Migration Assessment tool to help assess whether an application is capable of and/or encouraged for migration to the cloud. You’ll want to ensure that your applications will be secure and that your business will see a positive boost in performance.
2. Which Approach?
The most common approaches are either lifting and shifting applications (“rehost”) or completely developing a new architecture and design (“refactor” or “rearchitect”). Lift-and-shift can be done more quickly but with greater limitation.
Unless you use the Racemi platform to migrate and optimize applications at scale, using the rehost method lacks customization potential and the ability to fully utilize the cloud’s scalability and agility. Therefore, many older legacy systems would be better suited for the refactor method to develop and host the application more effectively. It can be more expensive and will take longer but will be the right choice in the long run for certain applications.
Make sure you do your due diligence regarding possible cloud migration strategies.
3. Assessment of Available Cloud Migration Tools:
There are many ways in which you can migrate to the cloud; lots of services from cloud providers and third parties that can help you to make the most from your migration.
Typically, when migrating to the cloud, there is quite a bit of data involved for an organization. There are both online data migration techniques and offline data migration techniques. Most public cloud providers offer both options and can help you determine which option is right for your business.
Offline data migration literally means putting data onto physical disks/drives and sending them to your cloud provider whereas online data migration is done through a network. As archaic as offline data migration may seem, it can be a more cost-effective way of migrating large amounts of information.
Bringing It All Together
Whatever you do, don’t just jump into it. Before deciding on your cloud migration needs, make sure to do your research and determine whether it is right for your applications. There are several other key steps you should take when crafting your cloud migration strategy.
