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 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 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 finances and agility. IT departments see the promise of the general public cloud as a possible technique 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 sources based mostly on their workload necessities. This feeds into the concept whereas conventional knowledge heart sources are finite (it’s a must 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 flexibility to make sources obtainable 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 flexibleness of the general public cloud presents the opportunity of faster transformation, probably resulting in progress quicker.
Q: What does it imply to maneuver purposes and workloads to the cloud?
A: Essentially the most fundamental technique to transfer purposes to the general public cloud is “raise and shift.” This implies shifting purposes and their workloads to the general public cloud with none modifications; you merely copy them out of your knowledge heart and shift them as-is to a public cloud setting.
Whereas this strategy is in style and easy, it’s a double-edged sword. Until 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 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 raise and shift, chances are you’ll be growing your prices from the get-go.
In case you do resolve emigrate an utility to the cloud, do you really want all of the sources 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 lure and overspend on storage that’s not tied to any compute, on too many reserved situations, or in different methods, resembling sustaining zombie VMs (VMs they’re utterly 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
In case you haven’t requested questions on how your utility 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 sources earlier than you’ve even moved your utility. It’s vital to know this data earlier than migration to verify the cloud arrange is optimized to assist 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 fairly than reactive. As an alternative of shifting an utility 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 impression general public cloud prices earlier than migrating the appliance to the cloud.
Let’s take a working example. Utilizing Intersight Workload Optimizer (Cisco’s utility 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 essentially the most appropriate cloud sources in 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 response to the billing and value changes that you’ve got negotiated together with your cloud supplier. Prices embody compute, service (resembling 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 sources with assured utility efficiency
- The price good thing about shifting workloads from on-demand to discounted pricing
- Reductions you can purchase
You may as well see the distinction in dangers (together with efficiency dangers, effectivity alternatives, and compliance dangers) in the event you merely raise 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 value comparability breakdown between raise 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 (resembling 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 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 data it gives.
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 means of particular eventualities.
