This weblog is the second in a collection on public cloud optimization. Additionally see “Scale back 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.
Lately 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 via 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 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 solution 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 will extra simply modify assets based mostly on their workload necessities. This feeds into the concept whereas conventional knowledge middle assets are finite (it’s a must 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 via the general public cloud is a game-changer to speed up innovation. Whereas conventional on-premises knowledge facilities carry extra baggage with value and complexity, the flexibleness of the general public cloud provides the potential of faster transformation, doubtlessly resulting in development sooner.
Q: What does it imply to maneuver purposes and workloads to the cloud?
A: Probably the most fundamental solution to transfer purposes to the general public cloud is “carry and shift.” This implies transferring purposes and their workloads to the general public cloud with none adjustments; you merely copy them out of your knowledge middle and shift them as-is to a public cloud setting.
Whereas this strategy is fashionable 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 attain, you don’t even know if transferring 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 transferring 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.
In case 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 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 cases, or in different methods, reminiscent of 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
In case 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 crucial to know this data earlier than migration to ensure the cloud arrange is optimized to help software efficiency on the lowest value.
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 transferring 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 parts that impression 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” 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 in 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 in line with the billing and value changes that you’ve got negotiated together with your cloud supplier. Prices embrace compute, service (reminiscent of 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 cases to make use of, combining environment friendly buy of assets with assured software efficiency
- The fee good thing about transferring workloads from on-demand to discounted pricing
- Reductions you should buy
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 offers 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 offers efficiency and cost-related suggestions together with particular actions to attain these financial savings (reminiscent of shopping for reserved cases, deleting volumes, scaling VMs, and optimizing reserved cases). It drills down into buy portions really useful, 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. Anybody can join the trial and use the cloud migration state of affairs planning functionality to see the kind of data it offers.
Detailed data 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 via particular eventualities.
