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 how one can simplify multi-cloud operations in AWS, Azure, and GCP.
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 way 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 finances 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 finances line merchandise or from spending much less as a result of they’ll extra simply regulate assets based mostly on their workload necessities. This feeds into the concept whereas conventional information heart assets are finite (you need 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 power to make assets out there to builders inside minutes by way of 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 pliability of the general public cloud gives the potential of faster transformation, probably resulting in development 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 information heart and shift them as-is to a public cloud surroundings.
Whereas this strategy is standard and easy, it’s a double-edged sword. Except 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 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 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 really want all of the assets you’re at present utilizing on-premises to make sure the appliance performs nicely 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, akin to sustaining zombie VMs (VMs they’re fully 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 information heart and optimized your workloads there, you then’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 essential 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 benefit from the guarantees of the cloud with out overspending?
A: I like to consider it as being proactive somewhat than reactive. As a substitute of shifting an software to the general public cloud after which asking how it may be optimized, the most effective 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 working example. Utilizing Intersight Workload Optimizer (Cisco’s software useful resource administration resolution), you are able to do “what-if” state of affairs 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 suggest shifting workloads from on-demand to discounted pricing and buying extra reductions.
The plan calculates prices in response to the billing and worth changes that you’ve got negotiated along with your cloud supplier. Prices embody compute, service (akin 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 situations to make use of, combining environment friendly buy of assets with assured software efficiency
- The fee good thing about shifting workloads from on-demand to discounted pricing
- Reductions you can purchase
You can too 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 necessary to do not forget that optimizing workloads for efficiency and value 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 (akin to shopping for reserved situations, deleting volumes, scaling VMs, and optimizing reserved situations). It drills down into buy portions really helpful, 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 resolution that features a free 45-day trial. Anybody can join the trial and use the cloud migration state of affairs planning functionality to see the kind of info it gives.
Detailed info on the state of affairs 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 way of particular situations.
