This weblog is the second in a sequence on public cloud optimization. Additionally see “Reduce Public Cloud Spend with Intersight Workload Optimizer,” and keep tuned for the third weblog within the sequence on tips on how to 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 supplied by the general public cloud by efficient cloud migration planning. The next is a recap of our dialog.


Q: Why are organizations shifting workloads to the cloud? 

A: For years now, organizations have been shifting 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 solution 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 will extra simply regulate assets based mostly on their workload necessities. This feeds into the concept whereas conventional information middle assets are finite (it’s important to buy extra {hardware} in case your necessities enhance), assets within the public cloud are infinite (you’ll be able to spin up assets on-demand with out investing in associated capital bills). As well as, the flexibility 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 information facilities carry extra baggage with price and complexity, the flexibleness of the general public cloud provides the opportunity of faster transformation, probably resulting in development quicker.


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

A: Essentially the most primary solution to transfer functions to the general public cloud is “raise and shift.” This implies shifting functions and their workloads to the general public cloud with none adjustments; you merely copy them out of your information middle and shift them as-is to a public cloud setting.

Whereas this strategy is in style and easy, it’s a double-edged sword. Until you’ve thought-about the aim and standing of your utility and what you’re aiming to attain, you don’t even know if shifting an utility to the cloud is the best choice. Some up-front evaluation may present that re-architecting, retaining, or retiring the applying could also be a greater strategic possibility than shifting it to the cloud. And in case you simply go forward with raise and shift, it’s possible you’ll be growing your prices from the get-go.

Should you do determine emigrate an utility to the cloud, do you really want all of the assets you’re at present utilizing on-premises to make sure the applying performs properly 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 situations, 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% in the course of the first 18 months of their new structure.”
–  GCN, March 2022

Should you haven’t requested questions on how your utility is performing in your information 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 utility. It’s important to know this info earlier than migration to verify the cloud arrange is optimized to assist utility efficiency on the lowest price.


Q: How can organizations make the most of the guarantees of the cloud with out overspending?

A: I like to consider it as being proactive slightly than reactive. As an alternative of shifting an utility to the general public cloud after which asking how it may be optimized, the most effective follow is to contemplate the person parts that affect general public cloud prices earlier than migrating the applying to the cloud.

Let’s take a working example. Utilizing Intersight Workload Optimizer (Cisco’s utility useful resource administration answer), 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 shifting workloads from on-demand to discounted pricing and buying extra reductions.

The plan calculates prices in accordance with the billing and value changes that you’ve got negotiated along with your cloud supplier. Prices embrace compute, service (comparable to IP companies), 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 situations to make use of, combining environment friendly buy of assets with assured utility efficiency
  • The price advantage of shifting workloads from on-demand to discounted pricing
  • Reductions you should buy

Cisco Intersight Workload Optimizer gives a comparability of raise and shift versus optimized workload migration to the general public cloud together with advisable actions to attain optimized efficiency when shifting to the cloud and on a steady foundation.

It’s also possible to see the distinction in dangers (together with efficiency dangers, effectivity alternatives, and compliance dangers) in case you merely raise and shift an utility to the general public cloud versus in case you optimize earlier than you progress the applying to the general public cloud. IWO additionally gives a value comparability breakdown between raise and shift and optimized utility migration.

It’s necessary to keep in mind that optimizing workloads for efficiency and price is an ongoing course of. When you’ve migrated to the cloud, IWO gives efficiency and cost-related suggestions together with particular actions to attain these financial savings (comparable to shopping for reserved situations, deleting volumes, scaling VMs, and optimizing reserved situations). It drills down into buy portions advisable, 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 answer 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 gives.

Detailed info on the situation planning is on the market 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 situations.
