This weblog is the second in a collection on public cloud optimization. Additionally see “Reduce Public Cloud Spend with Intersight Workload Optimizer,” and keep tuned for the third weblog within the collection on simplify multi-cloud operations in AWS, Azure, and GCP.

Just lately I sat down with Mohit Vaswani, technical options architect for Cisco Intersight Workload Optimizer (IWO), to speak about how organizations can obtain price advantages provided by the general public cloud by efficient cloud migration planning. The next is a recap of our dialog.


Q: Why are organizations transferring workloads to the cloud? 

A: For years now, organizations have been transferring functions to the general public cloud for a number of causes. One of many largest motivations is funds and agility. IT departments see the promise of the general public cloud as a possible strategy to decrease prices, both from eliminating capital bills and monitoring solely operational bills as a funds line merchandise or from spending much less as a result of they’ll extra simply modify assets primarily based on their workload necessities. This feeds into the concept that whereas conventional knowledge middle assets are finite (you must buy extra {hardware} in case your necessities improve), assets within the public cloud are infinite (you may spin up assets on-demand with out investing in associated capital bills). As well as, the power to make assets accessible to builders inside minutes by the general public cloud is a game-changer to speed up innovation. Whereas conventional on-premises knowledge facilities carry extra baggage with price and complexity, the flexibleness of the general public cloud affords the potential of faster transformation, doubtlessly resulting in development sooner.


Q: What does it imply to maneuver functions and workloads to the cloud?

A: Essentially the most primary strategy to transfer functions to the general public cloud is “elevate and shift.” This implies transferring functions and their workloads to the general public cloud with none modifications; you merely copy them out of your knowledge middle and shift them as-is to a public cloud setting.

Whereas this method is standard and easy, it’s a double-edged sword. Until you’ve thought of the aim and standing of your software and what you’re aiming to realize, you don’t even know if transferring an software to the cloud is the most suitable choice. Some up-front evaluation might present that re-architecting, retaining, or retiring the appliance could also be a greater strategic choice than transferring it to the cloud. And in the event you simply go forward with elevate and shift, chances are you’ll be growing your prices from the get-go.

Should you do resolve emigrate an software to the cloud, do you really want all of the assets you’re at the moment utilizing on-premises to make sure the appliance performs nicely as soon as it’s within the public cloud? Many organizations fall into this lure and overspend on storage that’s not tied to any compute, on too many reserved cases, or in different methods, comparable to sustaining zombie VMs (VMs they’re utterly unaware of, that don’t have house owners, or which have been deserted).

“45% of organizations that carry out a lift-and-shift migration will
overspend by 70% throughout the first 18 months of their new structure.”
–  GCN, March 2022

Should you haven’t requested questions on how your software is performing in your knowledge middle and optimized your workloads there, then you definately’re merely carrying over potential methods to over-spend within the public cloud. You’ve defeated the aim of optimizing public cloud assets earlier than you’ve even moved your software. It’s important to know this info earlier than migration to ensure the cloud arrange is optimized to assist software efficiency on the lowest price.


Q: How can organizations reap the benefits of the guarantees of the cloud with out overspending?

A: I like to consider it as being proactive somewhat than reactive. As an alternative of transferring an software to the general public cloud after which asking how it may be optimized, the perfect apply is to think about the person parts that influence total public cloud prices earlier than migrating the appliance to the cloud.

Let’s take a living proof. Utilizing Intersight Workload Optimizer (Cisco’s software useful resource administration resolution), you are able to do “what-if” situation planning for cloud migration. A Migrate to Cloud plan simulates migration of on-premises VMs to the cloud, or migration of VMs from one cloud supplier to a different. The plan focuses on optimizing efficiency and prices by selecting probably the most appropriate cloud assets on your VMs and the volumes they use. To additional optimize your prices, the plan can advocate transferring workloads from on-demand to discounted pricing and buying extra reductions.

The plan calculates prices based on the billing and value changes that you’ve negotiated along with your cloud supplier. Prices embrace compute, service (comparable to IP providers), and license prices. The plan additionally calculates low cost purchases for VMs that may profit from discounted pricing.

The plan outcomes present:

  • Projected prices
  • Actions to execute your migration and optimize prices and efficiency
  • Optimum cloud cases to make use of, combining environment friendly buy of assets with assured software efficiency
  • The price good thing about transferring workloads from on-demand to discounted pricing
  • Reductions you should buy

Cisco Intersight Workload Optimizer offers a comparability of elevate and shift versus optimized workload migration to the general public cloud together with really helpful actions to realize optimized efficiency when transferring to the cloud and on a steady foundation.

You can even see the distinction in dangers (together with efficiency dangers, effectivity alternatives, and compliance dangers) in the event you merely elevate and shift an software to the general public cloud versus in the event you optimize earlier than you progress the appliance to the general public cloud. IWO additionally offers a value comparability breakdown between elevate and shift and optimized software migration.

It’s necessary to keep in mind that optimizing workloads for efficiency and value is an ongoing course of. When you’ve migrated to the cloud, IWO offers efficiency and cost-related suggestions together with particular actions to realize these financial savings (comparable to shopping for reserved cases, deleting volumes, scaling VMs, and optimizing reserved cases). It drills down into buy portions really helpful, upfront prices, breakeven interval, and financial savings.

Q: How can somebody be taught extra about planning for cloud migration with Intersight Workload Optimizer?

A: Intersight Workload Optimizer is a SaaS resolution that features a free 45-day trial. Anybody can join the trial and use the cloud migration situation planning functionality to see the kind of info it offers.

Detailed info on the situation planning is accessible within the Cisco Intersight Workload Optimizer User Guide, and our cloud optimization specialists can be found for one-on-one demos to stroll by particular eventualities.
