Top Ten things to consider when moving Business Critical Applications (BCA) to the Cloud (Part 2 of 3)

In the first part we looked at public, private and Hybrid Cloud and their characteristics. In this part we will look at the common characteristics of business critical applications. We will also look at how some of these characteristics relate to the different types of Cloud infrastructure.

Common Characteristics of Business Critical Applications (BCA):

Business critical applications typically have very stringent SLAs and have a direct impact on the business. These are the crown jewels of the business that need to be managed with utmost care to avoid loss of productivity, data and potential revenue. These are the major factors can have a direct impact on these applications such as the following:

Top Ten things to consider when moving Business Critical Applications (BCA) to the Cloud (Part 1 of 3)

The cloud transformation is now for real. Customers have a stated long-term goal of running a majority of their applications in the cloud. Gartner predicts that public cloud services to grow by 16.5% in 2016. The highest growth area is cloud infrastructure, which is projected to grow at 38.4% in 2016. Today’s CIOs understand that a clear cloud strategy is a critical component of managing their information technology needs.

While developers have adapted to the cloud and its benefits, traditional enterprise business critical applications are not very prevalent in the cloud. Until recently most of these applications had not even been virtualized. Just in the past two to three years a majority of these enterprise applications have been virtualized. What are the unique characteristics of these applications that need to be considered for cloudification? In this three part blog series, we will analyze the top ten BCA requirements and how different types of cloud infrastructures satisfy them. In part 1 we will look at the different types of cloud infrastructures and their characteristics. Continue reading

Updated for vSphere 6 – SAP on VMware Best Practices guide

SAP production support for vSphere 6 was available from the latter half of last year – see http://scn.sap.com/docs/DOC-27384 . The best practices guide has been updated with the latest vSphere 6 information to help you with virtualizing SAP. Some of the new content includes:

  • Estimating SAPS of virtual machines and how this is aligned with ESXi scheduling behavior.
  • Updated analysis of high availability options for SAP in the virtual environment. This includes the use of VMware Fault Tolerance for SAP Central Services installed in a multi-vCPU virtual machine.
  • A section where all the best practices are summarized and categorized by different topics (CPU, memory, high availability etc.). For those already familiar with the vSphere concepts and use cases just skip to this section.

Certain topics like HANA and Business Objects have separate papers dedicated to them – these are referenced and the content is not repeated in this document.

The paper is available for download here.

Harnessing the Power of Storage Virtualization and Site Recovery Manager to Provide HA and DR Capabilities to Business Critical Databases – VAPP4634

Harnessing the Power of Storage Virtualization and Site Recovery Manager to Provide HA and DR Capabilities to Business Critical Databases – VAPP4634

How do you simplify and improve availability of your Extended distance Oracle Real Application Cluster using vSphere Metro Storage Cluster (vMSC) ?

Storage Virtualization, both host based and appliance based, can pave the way for increased ease of configuration and improved availability of your cluster based applications. vMSC features including vMotion, HA, DRS and FT as well as extended distance Oracle Real Application Clusters (RAC) are greatly simplified, and in some cases, made possible through the use of storage virtualization technologies such as EMC VPLEX, Netapp Metro Cluster, IBM SVC, HP 3PAR Peer Persistence , VMware vSAN or Oracle Automatic Storage Management (ASM) disk groups.

Site Recovery Manager with Oracle Data Guard can provide the much needed Disaster Recovery component thereby providing a complete HA and DR solution to Business Critical Databases

See where and how virtualized storage provided by above storage virtualization vendors and ASM are most effectively used to help protect your business critical applications virtualized on vSphere.

See how one Global 1000 company used storage virtualization to achieve 0 second RPO and 5 second RTO.

Details on the solution will be discussed in detail at VMworld 2015 Barcelona in session VAPP4634:

Virtual Volumes: A game changer for operations of virtualized business critical databases

This is first of a series of posts on deploying vSphere Virtual Volumes for Tier 1 Business Critical Databases. Although this article is written with a focus on Oracle databases, much of this discussion holds good for any Mission critical application.

Business critical databases are among the last workloads virtualized in enterprises, primarily because of the challenges that they pose with growth and scale. Typically the low hanging fruits are virtualizing the Development, Testing/QA, Staging databases after running a successful POC and then moving on the big guy’s i.e. the Production databases.

There are many common concerns about virtualizing business critical databases that inhibit and delay virtualization of these workloads:

  • Business critical virtualized databases need to meet strict SLAs for performance and storage has traditionally been the slowest component
  • Databases grow quickly, while at the same time there is a need to reduce backup windows and their impact on system performance.
  • There is a regular need to clone and refresh databases from production to QA and other environments. However, the size of the modern databases make it harder to clone and refresh data from production to other environments
  • Databases of different levels of criticality need different storage performance characteristics and capabilities.
  • There is a never-ending debate between DBAs and Systems administrators regarding filesystems VS raw devices and VMFS VS RDM. These are primarily due to some of the deficiencies that existed in the past with virtualization.

STO4452 – Virtual Volumes (VVOLS) a game changer for running Tier 1 Business Critical Databases

Virtual Volumes (VVOLS) a game changer for running Tier 1 Business Critical Databases:

One of the major components released with vSphere 6 this year was the support for Virtual Volumes (VVOLS). VVOLS has been gaining momentum with storage vendors, who are enabling its capabilities in their arrays.

When virtualizing business databases there are many critical concerns that need to be addressed that include:

1. Database Performance to meet strict SLAs
2. Daily Operations e.g. Backup & Recovery to complete in set window
3. Cut down time to Clone / Refresh of Databases from Production
4. Meet different IO characteristics and capabilities based on criticality
5. Never ending debate with DBAs : File Systems v/s Raw Devices , VMFS v/s RDM Continue reading

Disaster Recovery for Virtualized Business Critical Applications (Part 3 of 3)

Planned Migration:

One of the relatively newer use cases for SRM is planned migration. With this use case, customers can migrate their business critical workloads to the recovery or cloud provider sites in a planned manner. This could be in planning for an upcoming threat such as a hurricane or other disaster or an actual datacenter migration to a different location or cloud provider.

Protection Groups:

A protection group is a group of virtual machines that fail over together to the recovery site. Protection groups contain virtual machines whose data has been replicated by array-based replication or by VR. Typically contains virtual machines that are related in some way such as:

  • A three-tier application (application server, database server, Web server)
  • Virtual machines whose virtual machine disk files are part of the same datastore group.
