This weblog is the second in a collection on public cloud optimization. Additionally see “Cut back Public Cloud Spend with Intersight Workload Optimizer,” and keep tuned for the third weblog within the collection on easy methods to simplify multi-cloud operations in AWS, Azure, and GCP.
Not too long ago I sat down with Mohit Vaswani, technical options architect for Cisco Intersight Workload Optimizer (IWO), to speak about how organizations can obtain value advantages provided by the general public cloud via 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 greatest motivations is finances and agility. IT departments see the promise of the general public cloud as a possible option 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 modify assets based mostly on their workload necessities. This feeds into the concept whereas conventional knowledge 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 obtainable 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 quicker.
Q: What does it imply to maneuver functions and workloads to the cloud?
A: Probably the most fundamental option to transfer functions to the general public cloud is “carry and shift.” This implies shifting functions and their workloads to the general public cloud with none modifications; you merely copy them out of your knowledge middle and shift them as-is to a public cloud setting.
Whereas this method is well-liked 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 realize, you don’t even know if shifting an utility 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.
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 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 cases, or in different methods, equivalent to sustaining zombie VMs (VMs they’re utterly unaware of, that don’t have house owners, or which were 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
Should you haven’t requested questions on how your utility 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 utility. It’s vital to know this info earlier than migration to verify the cloud arrange is optimized to help utility 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 slightly than reactive. As a substitute of shifting an utility to the general public cloud after which asking how it may be optimized, one of the best follow 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 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 essentially 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 worth changes that you’ve negotiated along with your cloud supplier. Prices embody compute, service (equivalent 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 cases to make use of, combining environment friendly buy of assets with assured utility efficiency
- The price good thing about 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 utility 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 price comparability breakdown between carry and shift and optimized utility migration.
It’s essential 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 (equivalent to shopping for reserved cases, deleting volumes, scaling VMs, and optimizing reserved cases). It drills down into buy portions really helpful, 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 via particular situations.
