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 tips on how to simplify multi-cloud operations in AWS, Azure, and GCP.

Just 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 supplied 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 largest motivations is finances and agility. IT departments see the promise of the general public cloud as a possible method 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 alter sources primarily based on their workload necessities. This feeds into the concept whereas conventional knowledge middle sources are finite (you must 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 way 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 pliability of the general public cloud gives the potential for faster transformation, doubtlessly resulting in progress quicker.


Q: What does it imply to maneuver purposes and workloads to the cloud?

A: Probably the most primary method 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 adjustments; you merely copy them out of your knowledge middle and shift them as-is to a public cloud setting.

Whereas this method is fashionable and easy, it’s a double-edged sword. Except 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 best choice. Some up-front evaluation might present that re-architecting, retaining, or retiring the applying could also be a greater strategic choice than shifting it to the cloud. And if you happen to simply go forward with raise and shift, you could be rising your prices from the get-go.

If you happen to do determine 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 applying performs effectively 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, similar to 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% 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 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 sources earlier than you’ve even moved your utility. It’s essential to know this info earlier than migration to ensure the cloud arrange is optimized to help utility efficiency on the lowest price.


Q: How can organizations reap the benefits 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 most effective apply is to contemplate the person parts that impression general public cloud prices earlier than migrating the applying to the cloud.

Let’s take a working example. 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 line with the billing and value changes that you’ve got negotiated together with your cloud supplier. Prices embody compute, service (similar to 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 situations to make use of, combining environment friendly buy of sources with assured utility efficiency
  • The associated fee advantage of shifting workloads from on-demand to discounted pricing
  • Reductions you can purchase

Cisco Intersight Workload Optimizer offers a comparability of raise and shift versus optimized workload migration to the general public cloud together with beneficial actions to realize optimized efficiency when shifting to the cloud and on a steady foundation.

It’s also possible to see the distinction in dangers (together with efficiency dangers, effectivity alternatives, and compliance dangers) if you happen to merely raise and shift an utility to the general public cloud versus if you happen to optimize earlier than you progress the applying to the general public cloud. IWO additionally offers 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 offers efficiency and cost-related suggestions together with particular actions to realize these financial savings (similar to 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 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 info it offers.

Detailed info on the state of affairs planning is accessible 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.
