If you have been running your infrastructure for years, migrating to the cloud may seem overwhelming. It is hard to give up control and trust your services and data to someone else. It can be a complicated effort to perform a cloud migration, but there are some simple guidelines that you can follow to make the migration process smoother.
Decide Which Systems Are Going To Migrate Where
You have several options when transitioning to the cloud:
- On-premise server or database migration to cloud platforms
- Migrating on-premise applications to the cloud (their cloud equivalent)
- Purchasing licenses for cloud-based services that offer better features than what you currently have on-premise.
Any variation of these choices can also be selected. Your choices could be based on expenditures, features, ease of use, reliability, and availability. Do not forget to include key stakeholders in determining where to migrate. Make sure that you do not sacrifice any features that might have been accessible with the on-premise version of the program if you want to move an on-premise application to its cloud counterpart.
Your Choices Should Support Open Standards
As an enterprise, being able to configure systems and integrate with other systems can become essential to your operational development. While you do not currently see the need, as their company grows, many organizations find integrating systems essential. It is also important to ensure the open standards are supported by the systems you select. Developing and maintaining custom connections can be expensive. Several cloud technologies support open standards that are simpler to link to and customize, such as:
- Security Assertion Markup Language (SAML), a standard of federated identity used for authentication, or
- System for Cross-domain Identity Management (SCIM), a common API used to handle users.
Security And Compliance Management
Migrating to the cloud will present new challenges for security. There is more than just an extra network that needs to be protected when introducing a hybrid infrastructure. Ensure that you are migrating to comply with the government as well as industry compliance requirements, regardless of platforms, services, and applications. For instance, in Europe, government user data laws are known as the General Data Protection Regulation (GDPR) and in California, the California Consumer Privacy Act (CCPA). You would need to ensure that the cloud solutions to which you are migrating are compatible if your customers live in either of these areas.
Federate User Identities
The majority of on-site Identity and Access Management (IAM) systems that are used to access the on-site applications you have hosted will not be able to move to the cloud easily. You will need to make sure that it is still possible to centrally manage and authenticate all your users. Choosing a cloud-based IAM device is your best option.
Migrate To The Cloud In Phases
Most significantly, you need to realize that it can be a long process to migrate to the cloud and should be scheduled in phases. It can be a strong first step to migrate to a cloud-based IAM system that can integrate with your on-premise authentication system. Thus, you can quickly reconfigure the authentication flow when you move the other applications to cloud platforms, and your users can find the change much less painful.
It can be a time consuming and drawn out process to migrate to the cloud. First, make sure that you have a consistent strategy and a well thought out project plan for cloud migration. To reevaluate your progress up to that point and change as appropriate, create milestones in the plan. This might appear like a daunting task, but you can eventually find that both time and money can be saved with this.
