If you are considering migrating SAP HANA to Amazon Web Services (AWS), then this article is for you. It is a good idea to migrate SAP HANA to AWS, as the AWS migration process is a pretty straightforward one. This is because you’re already using SAP HANA. For the migration process, all you need to do is map your existing SAP HANA systems and sizing across different platforms to SAP HANA solutions on AWS. The best way to know your options and embark on a seamless migration process is to consult an Amazon Web Services consultant. However, before you opt for Amazon cloud services, here is what you should know about the migration process.
What is SAP HANA?
For the uninitiated, SAP HANA is an in-memory solution for relational database management. In comparison to conventional RDBMS systems, data can be retrieved from HANA with much higher performance as it is based on a columnar structure and saves all data in memory. Next-generation applications, business intelligence, and analytics frequently use the solution.
Running SAP HANA on AWS
Cloud infrastructure services from Amazon Web Service (AWS) enable SAP HANA to be highly available, fault-tolerant, and reasonably priced. You can fully benefit from the flexibility and security of the AWS ecosystem by moving HANA to the AWS cloud. Application management is simpler when running SAP HANA on AWS, as opposed to your local data center. For instance, all users need to worry about is administering their SAP applications on AWS, while AWS is responsible for managing the physical infrastructure. That means you have fewer headaches to deal with. Additionally, users of AWS only need to pay for actual consumption. In other words, you can hire the technology and spend in terms of hourly rates. Additionally, AWS offers SAP BYOL (bring your own license), which can help to further reduce costs.
Two main architectures you should know
When it comes to running SAP HANA on AWS, you need to know about two main supported architectures. They are Single-AZ and Multi-AZ (HA)
Benefits of running SAP on AWS
There are numerous benefits associated with running SAP HANA on AWS. They include, but are not restricted to:
- Single-AZ, single-node architecture: This particular option helps you configure a single EC2 instance to host SAP HANA using Amazon EBS storage. It also offers you an OS (operating system) of your choice.
- Multi-AZ (HA), single-node architecture: This alternate option allows you to provision two EC2 instances in private subnets across two different availability zones, all with Amazon EBS storage. The architecture is based on the SLES HAE (High Availability Extension), which is part of the SAP SLES OS.
- Superior speed and agility
- You need to only bear operating expenses instead of capital expenses
- You get access to an extensive partner ecosystem with dedicated AWS cloud support
- AWS offers a 99.99 percent service-level agreement (SLA) for large instances in a high-availability pair, and a 99.9 percent SLA for a single SAP HANA large instance.
