Azure offers vast capabilities to effectively store substantial data volumes generated by SAP workloads. With the advent of cloud technologies, cost-saving has become a significant point of consideration. Here, we’ll outline vital means to optimize storage costs in Azure for SAP workloads.
1. Understand and Utilize Appropriate Storage Tiers
Azure offers different storage tiers―Hot, Cool, and Archive, each uniquely positioned to cater to different usage scenarios. The Hot tier offers high performance, suited for frequently accessed data, the Cool tier, cost-effective for infrequently accessed data, and Archive, the most economical tier for long-sitting, rarely accessed data.
SAP workloads often comprise a mix of frequently accessed (transactional data) and not so frequently accessed data (backup, or reports). Implementing a tiering strategy based on data usage can significantly cut down on storage costs.
| Storage Tier | Suitability |
|---|---|
| Hot | Frequently accessed data, such as running transaction data |
| Cool | Infrequently accessed data, such as old reports |
| Archive | Rarely accessed data, such as old backups |
2. Leverage Azure Hybrid Benefit
Azure Hybrid Benefit (AHB) allows you to bring your on-premises Windows Server and SQL Server licenses with active Software Assurance or subscriptions to Azure. AHB can significantly reduce costs up to 40% on Windows Server VMs. For SAP workloads running on SQL Server, this benefit can cut down expenses substantially.
3. Right-size your VMs (Virtual Machines)
Selecting the correct VM size is important. Over-provisioning leads to higher costs, while under-provisioning might result in poor performance. Microsoft provides a wide variety of Azure VMs optimized for SAP workloads.
For example, the ‘Esv3’ series VMs are suitable for general-purpose SAP applications and ‘Mv2’ series VMs for memory-intensive applications, like SAP HANA. Understanding workload requirements and selecting suitable VMs can help optimize costs.
4. Use Reserved Instances
Reserved Instances offer significant discounts over pay-as-you-go pricing models. In exchange for committing to a one- or three-year term, you can reduce costs by up to 72%. Since SAP workloads tend to persist over long stretches, using Reserved Instances can lead to significant savings.
Cost optimization in Azure is an ongoing process requiring constant monitoring and management. By understanding the pricing models, utilizing the right storage tiers, leveraging hybrid benefits, and managing VM sizes, we can strategically optimize storage costs for SAP workloads in Azure. Practicing these strategies can prove beneficial, not just for the sake of acing the AZ-120 exam, but also for efficiently managing real-world Azure environments.
Practice Test
True or False: Azure NetApp Files can help optimize storage costs in a SAP environment.
- True
- False
Answer: True
Explanation: Azure NetApp Files provides industry-leading performance and security for your SAP workloads and can optimize storage costs by consolidating multiple workloads.
When storing data in Azure, using infrequently accessed data tier can help in minimizing storage costs.
- True
- False
Answer: True
Explanation: Azure has options like Cool and Archive access tiers for infrequently accessed data which costs less compared to Hot access tier.
Which of the following methods can help in optimizing storage costs? (Select all that apply)
- A) Using Azure Cost Management
- B) Reducing the amount of data stored
- C) Setting data to never expire
- D) Implementing Azure Storage Reserved Capacity
Answer: A, B, D
Explanation: Azure Cost Management provides visibility into where you’re incurring cost in your Azure resources. Reducing data stored and implementing Reserved Capacity can lower costs. However, setting data to never expire can lead to unnecessary costs for unneeded data.
The term ‘Blob Storage’ refers to a kind of storage that is optimized to store massive amounts of unstructured data.
- True
- False
Answer: True
Explanation: Blob Storage is designed for storing large amounts of unstructured data like text or binary data, which can help reduce costs.
Azure Policy cannot be used to enforce budget goals and optimize storage costs for SAP workloads.
- True
- False
Answer: False
Explanation: Azure Policy can be utilized to enforce budget goals by setting policy definitions to limit the resources and thereby optimizing storage costs.
Which storage account type in Azure offers the lowest storage costs?
- A) Premium performance
- B) Standard performance
- C) Archive storage
- D) Disk storage
Answer: C) Archive storage
Explanation: Archive storage offers the lowest storage cost but it has the highest data retrieval costs, making it ideal for long-term backup and archival storage.
True or False: Snapshots in Azure are free.
- True
- False
Answer: False
Explanation: Snapshots do have a cost in Azure storage, which can be minimized with incremental snapshots that store only changes made after the previous snapshot.
Azure Spot virtual machines (VMs) are a cost-effective choice for workloads that can tolerate interruptions.
- True
- False
Answer: True
Explanation: Azure Spot VMs allows you to take advantage of unused capacity at a significant cost savings.
Hot Tier in Azure storage is recommended for:
- A) Frequently accessed data
- B) Archiving data
- C) Infrequently accessed data
- D) Data backup
Answer: A) Frequently accessed data
Explanation: The Hot access tier in Azure storage is optimized for storing data that is accessed frequently.
When working with Azure for SAP Workloads, all data should be stored in a single region to minimize costs.
- True
- False
Answer: False
Explanation: Although storing data in a single region might reduce transfer costs, it puts data at risk and contradicts good practices for redundancy and disaster recovery.
Interview Questions
What is the purpose of the Azure NetApp Files service in regards to SAP implementations in Azure?
Azure NetApp Files enables the deployment of SAP HANA and NetWeaver-based workloads on Azure, while optimizing the storage costs. It allows high-performance file storage, ensuring low latency for the SAP applications.
How does the Azure Site Recovery service help in optimizing storage costs for SAP on Azure?
Azure Site Recovery, a disaster recovery as a service (DRaaS), helps to automate the replication of Azure VMs to a separate location. It minimizes the costs associated with maintaining a separate physical disaster recovery site and storage infrastructure.
How can Azure Automated Backup be used to minimize storage costs for SAP environments?
Azure Automated Backup provides a cost-effective, automated backup solution for SAP HANA databases. It optimizes storage by only backing up new or changed data, which minimizes storage consumption.
How can Azure storage service tiers help to optimize storage costs for SAP on Azure?
Azure provides different service tiers – frequently accessed data (hot), infrequently accessed data (cool), and archived data (archive). These service tiers allow businesses to store data cost-effectively based on how often they access it.
