Hosting systems on more traditional infrastructure on-premises can tie up valuable IT resources required in supporting and maintaining the hardware.

There can also be more potential security and business continuity challenges by adopting local practices and technologies, rather than utilizing the more sophisticated security and back-up solutions available.

Options for cloud include running your own cloud environments on private or public cloud infrastructure (IaaS), running your applications on a platform (Platform as a Service – PaaS) or simply consuming the software or application as a service, delivered straight to the user desktop (SaaS).

In this article I offer you two sets of tips – firstly about sap migration to cloud and secondly more specifically about SAP migration to azure cloud.

When developing these tips I considered Gartner’s 5R model – which was widely promoted back in 2010 when cloud was just emerging – and whether it is still relevant when SAP MIGRATION. Much has changed in 10 years, so I’ve kept them in mind whilst also including my experience over that time and updated where needed.

Tips for Moving SAP Apps to Cloud

Here are five tips developed from lessons learnt by customers that have previously moved to the cloud:

  1. Understand suitability and migration efforts.
    Before moving to IaaS assess the complexity of your SAP workloads, the underlying infrastructure, the size of each workload and related databases – in terms of velocity, volume and variety – and the requirements for seasonal elasticity.
  2. Clean out your closet.
    Moving to the cloud is an opportunity to throw out the stuff you’re not using. When you owned that old on-premises server, it didn’t matter how much you had buried in there. When you’re on the cloud, the cost of carrying around a lot of dead weight can add up fast.
  3. Ensure that you don’t over-provision your virtual machines.
    It’s important to make sure that you provision enough resources so that you don’t have to keep increasing your system weekly.
  4. Balance security needs with the ability to troubleshoot.
    In a cluster installation, consider how you balance security with the ability to troubleshoot. A best practice is to open only the ports that are really needed. You might want the environment to be somewhat open to help with troubleshooting, but you don’t want it to be too open.
  5. Capture all application and data legal requirements during planning.
    Complying with legal requirements for data safety and security can be complicated, so it’s a good idea to work with the stakeholders and data owners for each application to capture all corporate and legal compliance needs. Plan for this up front.

Of course, there are different types of cloud that can run workloads or apps and IaaS suits organisations that want to run their own cloud environments, provisioning and managing their own Virtual Machines (Servers) and network infrastructure.

For users that don’t want the hassles of setting up and managing infrastructure, PaaS is popular, especially for organisations that want to manage their own Apps without worrying about managing the platforms that run them.

Some SAP users may wish to bring their own SAP licenses or want to be in control of their own applications but don’t want to have to invest in the skills required to manage the SAP BASIS layers, or worry about the compliance of SAP Certified backups/replication.

The lowest touch approach for organisations is to consume the software or application ‘as a service’ where the App is delivered straight to the user desktop (SaaS). Users don’t need to worry about software updates or anything that is required to run the software, they just consume it.

Multi-cloud is about using the best solution to fit a particular scenario. One size does not fit all, clients should consider the most appropriate type of solution be it IaaS, PaaS or SaaS as well as Private and Public Cloud to meet their business need. Utilising the best combination of multi-cloud solutions will increase overall performance, reduces costs and vendor lock in.

Here are five more tips, adapted from a Microsoft guide, for clients that want to move their SAP applications to Microsoft Azure Public Cloud:

  1. Consider moving low-risk systems to Azure with the vertical strategy right away.
    In evaluating when to use a vertical strategy, keep in mind that a low-risk end-to-end system might be a good candidate for testing this strategy and gaining experience with a production environment in Azure.
  2. Understand sap cloud migration strategy and how they can be best applied to your environment.
    Understanding what to move and when to move it is a big part of sap migration to azure cloud. The horizontal and vertical strategies discussed in Strategies for migrating SAP systems to Microsoft Azure provide practical, business-friendly guidance.
  3. Consider optimising your SAP environment before and after moving to Azure.
    You can optimise your environment before migrating by ensuring that retired systems aren’t migrated, that your SAP infrastructure inventory is accurate and that your disaster recovery plan is tested and in place. You don’t want to waste sap data migration time on systems or data you don’t need.
  4. Design for high availability in your production systems
    SAP systems have different elements to them from the application itself, the middleware, the database and the server operating systems.  Each of these will require a different approach to the High Availability design or the Disaster Recover technology. Consider Windows Server Failover Clustering, SQL Server Always On and SAP features like logon groups, remote function call groups and batch server groups.  The database may require specialised SAP database replication tools to ensure data is protected.
  5. Always keep security in mind.
    Protecting business data is a top priority. When migrating SAP workloads to Azure, consider all the compliance and data security aspects of hosting data in the public cloud.
