Moving Legacy Apps To The Hybrid Cloud
More legacy apps are moving to the cloud every day. Within two years, 34% of enterprises will have 60% or more of their apps on a cloud platform. The question then becomes, which type of cloud is needed for your legacy apps?
Migrating to hybrid cloud can give you the best of both public and private cloud, allowing certain processes to be on the more easily scalable public cloud while other processes are kept on the more secure private side.
Selecting The Right Cloud For Your Needs
One of the most important factors for cloud success is to make sure you pick the right applications to be moved to the cloud. In order to do this, you must have a good understanding of what each application does and then assess the business case for migrating it to the cloud.
Once you’ve decided which applications make sense, you can then decide which parts need public versus private cloud to create a hybrid cloud implementation.
Before you get started, make sure you have a good understanding of the differences between traditional software architectures and hybrid cloud platforms. These platforms are going to have both a public and private side, and in some cases, may have more than one of each.
Using hybrid cloud, you have the option to move your workload between the public and private platforms. You also have the ability to partition your applications so that certain components will reside on the public side and others on the private side.
A great example of hybrid cloud would be processes that require large storage systems which make sense to run on a public cloud to reduce costs. At the same time, you may have sensitive data (i.e. medical, financial, etc.) that needs to be close to the end user so it makes more sense to be on the private side.
You can incorporate a ranking system to help you select which applications should be moved. This can be based on:
- The ease of moving the app to hybrid cloud
- The importance of the app to the business
- The cost of developing a new app
- Benefits of moving the app
- The existing app architecture
- Compliance and Security requirements
Business continuity is an important factor in deciding which apps to move to hybrid cloud. If you have critical services that are required to keep your business alive, it might be a good idea to move them to hybrid cloud.
As part of this verification process, you’ll want to make sure your public cloud provider furnishes redundant services as part of their infrastructure. This will allow outages at a primary data center to failover to secondary centers without any interruption to their services.
You also have the option of building business continuity directly into your application. This will require taking the time and money to modify your application so that it provides these services. It may require having data stored in multiple places as well as keeping certain processes running in multiple locations at all times.
It’s a big decision to move to hybrid cloud, which is why it’s critical to pick a team that understands the intricacies of hybrid. Motifworks can help you decide which apps are right to move to the cloud and where they will fit into a hybrid cloud environment.
