This weblog is the second in a sequence on public cloud optimization. Additionally see “Cut back Public Cloud Spend with Intersight Workload Optimizer,” and keep tuned for the third weblog within the sequence on learn 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 means of 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 purposes to the general public cloud for a number of causes. One of many greatest 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 will extra simply regulate assets primarily based on their workload necessities. This feeds into the concept whereas conventional knowledge heart assets are finite (it’s a must to buy extra {hardware} in case your necessities improve), assets within the public cloud are infinite (you possibly can spin up assets on-demand with out investing in associated capital bills). As well as, the flexibility to make assets out there to builders inside minutes by means of 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 pliability of the general public cloud gives the opportunity of faster transformation, probably resulting in progress quicker.
Q: What does it imply to maneuver purposes and workloads to the cloud?
A: Probably the most primary strategy to transfer purposes to the general public cloud is “carry and shift.” This implies shifting purposes and their workloads to the general public cloud with none adjustments; you merely copy them out of your knowledge heart and shift them as-is to a public cloud setting.
Whereas this method is in style and easy, it’s a double-edged sword. Until you’ve thought-about 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 most suitable choice. Some up-front evaluation may present that re-architecting, retaining, or retiring the appliance could also be a greater strategic choice than shifting it to the cloud. And in the event you simply go forward with carry and shift, you might be growing your prices from the get-go.
If you happen to do resolve emigrate an software to the cloud, do you actually need all of the assets you’re presently utilizing on-premises to make sure the appliance 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, corresponding to sustaining zombie VMs (VMs they’re utterly unaware of, that don’t have homeowners, 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
If you happen to haven’t requested questions on how your software is performing in your knowledge 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 vital to know this info earlier than migration to ensure the cloud arrange is optimized to help 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 fairly than reactive. As an alternative of shifting an software to the general public cloud after which asking how it may be optimized, one of the best follow is to think about the person components that affect 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 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 essentially the most appropriate cloud assets on your VMs and the volumes they use. To additional optimize your prices, the plan can suggest shifting workloads from on-demand to discounted pricing and buying extra reductions.
The plan calculates prices in accordance with the billing and worth changes that you’ve got negotiated together with your cloud supplier. Prices embody compute, service (corresponding 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 software efficiency
- The fee advantage of shifting workloads from on-demand to discounted pricing
- Reductions you can purchase

You may also see the distinction in dangers (together with efficiency dangers, effectivity alternatives, and compliance dangers) in the event you merely carry 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 gives a value comparability breakdown between carry and shift and optimized software migration.
It’s essential to do not forget 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 realize these financial savings (corresponding to shopping for reserved situations, deleting volumes, scaling VMs, and optimizing reserved situations). It drills down into buy portions beneficial, 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 offered within the Cisco Intersight Workload Optimizer User Guide, and our cloud optimization specialists can be found for one-on-one demos to stroll by means of particular eventualities.
