This weblog is the second in a collection on public cloud optimization. Also see “Reduce Public Cloud Spend with Intersight Workload Optimizer,” and keep tuned for the third weblog within the collection on the right way to simplify multi-cloud operations in AWS, Azure, and GCP.
Recently I sat down with Mohit Vaswani, technical options architect for Cisco Intersight Workload Optimizer (IWO), to speak about how organizations can obtain value advantages supplied by the general public cloud by way of efficient cloud migration planning. The following is a recap of our dialog.
Q: Why are organizations shifting workloads to the cloud?
A: For years now, organizations have been shifting purposes to the general public cloud for a number of causes. One of the most important motivations is price range and agility. IT departments see the promise of the general public cloud as a possible method to decrease prices, both from eliminating capital bills and monitoring solely operational bills as a price range line merchandise or from spending much less as a result of they will extra simply alter assets primarily based on their workload necessities. This feeds into the concept whereas conventional information heart assets are finite (it’s important to buy extra {hardware} in case your necessities enhance), assets within the public cloud are infinite (you possibly can spin up assets on-demand with out investing in associated capital bills). In addition, the flexibility to make assets out there to builders inside minutes by way of the general public cloud is a game-changer to speed up innovation. While conventional on-premises information facilities carry extra baggage with value and complexity, the flexibleness of the general public cloud presents the opportunity of faster transformation, probably resulting in development sooner.
Q: What does it imply to maneuver purposes and workloads to the cloud?
A: The most simple method to transfer purposes to the general public cloud is “lift and shift.” This means shifting purposes and their workloads to the general public cloud with none adjustments; you merely copy them out of your information heart and shift them as-is to a public cloud atmosphere.
While this strategy is in style and easy, it’s a double-edged sword. Unless you’ve thought of the aim and standing of your software and what you’re aiming to realize, you don’t even know if shifting an software to the cloud is the best choice. Some up-front evaluation may present that re-architecting, retaining, or retiring the appliance could also be a greater strategic possibility than shifting it to the cloud. And when you simply go forward with raise and shift, you might be growing your prices from the get-go.
If you do resolve emigrate an software to the cloud, do you really want all of the assets you’re at present utilizing on-premises to make sure the appliance performs effectively as soon as it’s within the public cloud? Many organizations fall into this entice and overspend on storage that’s not tied to any compute, on too many reserved situations, or in different methods, equivalent to sustaining zombie VMs (VMs they’re fully unaware of, that don’t have house owners, or which were deserted).
“45% of organizations that perform a lift-and-shift migration will
overspend by 70% during the first 18 months of their new architecture.”
– GCN, March 2022
If you haven’t requested questions on how your software is performing in your information heart and optimized your workloads there, then you definitely’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 crucial to know this info earlier than migration to verify the cloud arrange is optimized to help software efficiency on the lowest value.
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 reasonably than reactive. Instead of shifting an software to the general public cloud after which asking how it may be optimized, the very best observe is to think about the person components that impression total public cloud prices earlier than migrating the appliance to the cloud.
Let’s take a living proof. Using Intersight Workload Optimizer (Cisco’s software 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 keeping with the billing and value changes that you’ve negotiated together with your cloud supplier. Costs embrace compute, service (equivalent 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
- Optimal cloud situations to make use of, combining environment friendly buy of assets with assured software efficiency
- The value good thing about shifting workloads from on-demand to discounted pricing
- Discounts you can purchase
You may see the distinction in dangers (together with efficiency dangers, effectivity alternatives, and compliance dangers) when you merely raise and shift an software to the general public cloud versus when you optimize earlier than you progress the appliance to the general public cloud. IWO additionally gives a price comparability breakdown between raise and shift and optimized software migration.
It’s vital to keep in mind that optimizing workloads for efficiency and price is an ongoing course of. Once you’ve migrated to the cloud, IWO gives efficiency and cost-related suggestions together with particular actions to realize these financial savings (equivalent 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 study 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. Anyone 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 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 way of particular situations.
