This weblog is the second in a sequence on public cloud optimization. Additionally see “Scale back 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 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 price range and agility. IT departments see the promise of the general public cloud as a possible approach 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’ll extra simply alter sources primarily based on their workload necessities. This feeds into the concept that whereas conventional information middle sources are finite (you need to buy extra {hardware} in case your necessities enhance), sources within the public cloud are infinite (you’ll be able to spin up sources on-demand with out investing in associated capital bills). As well as, the power to make sources out there to builders inside minutes by 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 flexibleness of the general public cloud gives the potential of faster transformation, doubtlessly resulting in progress sooner.
Q: What does it imply to maneuver functions and workloads to the cloud?
A: Essentially the most primary approach 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 information middle and shift them as-is to a public cloud surroundings.
Whereas this strategy is common and easy, it’s a double-edged sword. Except you’ve thought of 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 best choice. Some up-front evaluation might present that re-architecting, retaining, or retiring the appliance could also be a greater strategic choice than shifting it to the cloud. And when you simply go forward with carry and shift, you could be rising your prices from the get-go.
When you do resolve emigrate an utility to the cloud, do you really want all of the sources you’re at the moment utilizing on-premises to make sure the appliance performs nicely 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, equivalent to sustaining zombie VMs (VMs they’re fully unaware of, that don’t have homeowners, or which were deserted).
“45% of organizations that carry out a lift-and-shift migration will
overspend by 70% through the first 18 months of their new structure.”
– GCN, March 2022
When you haven’t requested questions on how your utility is performing in your information middle 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 sources earlier than you’ve even moved your utility. It’s essential to know this data earlier than migration to ensure the cloud arrange is optimized to help utility efficiency on the lowest price.
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 somewhat than reactive. As an alternative of shifting an utility to the general public cloud after which asking how it may be optimized, the perfect apply is to think about the person parts that affect general 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” 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 sources 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 keeping with the billing and worth changes that you’ve negotiated together 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 sources with assured utility efficiency
- The price good thing about shifting workloads from on-demand to discounted pricing
- Reductions you should buy
You can even see the distinction in dangers (together with efficiency dangers, effectivity alternatives, and compliance dangers) when you merely carry and shift an utility to the general public cloud versus when you optimize earlier than you progress the appliance to the general public cloud. IWO additionally offers 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 offers 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 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 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 Consumer Information, and our cloud optimization specialists can be found for one-on-one demos to stroll by particular eventualities.
