Attending to the Cloud: How IWO may also help you intend cloud migration

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 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 price advantages supplied 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 functions to the general public cloud for a number of causes. One of many largest motivations is price range 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 price range line merchandise or from spending much less as a result of they will extra simply alter sources based mostly on their workload necessities. This feeds into the concept that whereas conventional information heart sources are finite (you must buy extra {hardware} in case your necessities improve), sources within the public cloud are infinite (you may spin up sources on-demand with out investing in associated capital bills). As well as, the power to make sources accessible to builders inside minutes by means of 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 pliability of the general public cloud affords the potential for faster transformation, probably resulting in development sooner.


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

A: Essentially the most fundamental technique to transfer functions to the general public cloud is “raise and shift.” This implies shifting functions and their workloads to the general public cloud with none adjustments; you merely copy them out of your information heart and shift them as-is to a public cloud atmosphere.

Whereas this method is in style and easy, it’s a double-edged sword. Except you’ve thought of the aim and standing of your software and what you’re aiming to attain, you don’t even know if shifting an software to the cloud is the most suitable choice. Some up-front evaluation may present that re-architecting, retaining, or retiring the applying could also be a greater strategic choice than shifting it to the cloud. And in case you simply go forward with raise and shift, you could be growing your prices from the get-go.

If you happen to do resolve emigrate an software to the cloud, do you really want all of the sources you’re at present utilizing on-premises to make sure the applying 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, comparable to sustaining zombie VMs (VMs they’re fully 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% 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 software is performing in your information heart 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 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 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 fairly than reactive. As a substitute of shifting an software 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 affect total public cloud prices earlier than migrating the applying to the cloud.

Let’s take a working example. Utilizing Intersight Workload Optimizer (Cisco’s software 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 probably the most appropriate cloud sources in 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 response to the billing and worth changes that you’ve got negotiated along with your cloud supplier. Prices embrace compute, service (comparable 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 cases to make use of, combining environment friendly buy of sources with assured software 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 attain optimized efficiency when shifting to the cloud and on a steady foundation.

You can even see the distinction in dangers (together with efficiency dangers, effectivity alternatives, and compliance dangers) in case you merely raise and shift an software to the general public cloud versus in case you 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 software 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 attain these financial savings (comparable 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 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 offers.

Detailed data on the state of affairs planning is on the market within the Cisco Intersight Workload Optimizer User Guide, and our cloud optimization specialists can be found for one-on-one demos to stroll by means of particular eventualities.
