SAP HANA on Cloud [3 considerations before hosting]
High-speed data analytics is changing the way companies compete, enabling them to generate real-time insights to support their most important business processes. The SAP HANA* platform is a clear leader in this arena, providing a uniquely fast and adaptable platform for real-time business on an enterprise scale. Cloud computing offers a complementary technology that also provides game-changing capabilities. Let’s see what are the three considerations that need to be taken into an account:
1) Choose a single cloud or go multi-cloud
Optimizing your application to work with a specific cloud provider is relatively simple. Your development teams have just one set of cloud APIs to learn, and your application can take advantage of everything your chosen cloud provider offers.
Once you’ve updated your application to work with only one provider, moving your application to a different provider could require just as much effort as the original cloud migration. Additionally, having a single cloud provider might negatively impact your ability to negotiate important terms—such as pricing and SLAs—with the cloud provider.
One application in one cloud; another application in a different cloud. Perhaps the simplest multi-cloud approach runs one set of applications in one cloud provider and another set in another. This approach gives you increased business leverage with multiple providers as well as flexibility for where to put applications in the future. It also lets you optimize each application for the provider on which it runs.
2) Establish cloud KPIs
The best KPIs for a cloud migration show how your in-progress migration is going on, floodlighting visible or invisible problems that may be concealed within your application. Most important, perhaps, cloud migration KPIs can help you determine when the migration is complete and successful.
There are several key categories of cloud migration KPIs:
3) Let’s discover the shared data responsibility Model?
When your data is in your own data centres, the IT organization is responsible for protecting the data. But as you move data to the public cloud, the ownership line becomes fuzzy. The responsibility of data protection becomes shared between the cloud provider and you. Broadly speaking, cloud providers are responsible for the security of the cloud itself, while customers are responsible for security and compliance requirements for their data in the cloud. In GDPR-speak, you are generally the “controller” of your data and take on all the compliance and regulatory requirements associated with your end users’ data. Therefore, your greatest cloud security needs are around monitoring and restricting access to your data.
To elaborate further, the physical security of data centres and hardware is fully owned by the cloud provider. The cloud provider also controls and secures the host operating system and the virtualization layer. While some responsibilities are shared between you and the cloud service provider, others are entirely your responsibility.
