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

This weblog is the second in a collection on public cloud optimization. Additionally see “Scale back Public Cloud Spend with Intersight Workload Optimizer,” and keep tuned for the third weblog within the collection on the way 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 value 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 transferring workloads to the cloud? 

A: For years now, organizations have been transferring functions to the general public cloud for a number of causes. One of many greatest motivations is funds 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 funds line merchandise or from spending much less as a result of they will extra simply modify sources based mostly on their workload necessities. This feeds into the concept 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 means of the general public cloud is a game-changer to speed up innovation. Whereas conventional on-premises information facilities carry extra baggage with value and complexity, the pliability of the general public cloud affords the potential for faster transformation, probably resulting in progress quicker.


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 “elevate and shift.” This implies transferring 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 setting.

Whereas this strategy is standard 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 realize, you don’t even know if transferring an software to the cloud is the best choice. Some up-front evaluation may present that re-architecting, retaining, or retiring the applying could also be a greater strategic choice than transferring it to the cloud. And in the event you simply go forward with elevate and shift, you might be rising your prices from the get-go.

In case you do determine emigrate an software 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 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 situations, or in different methods, similar 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

In case you haven’t requested questions on how your software is performing in your information middle and optimized your workloads there, you then’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 info earlier than migration to ensure the cloud arrange is optimized to assist software efficiency on the lowest value.


Q: How can organizations benefit from the guarantees of the cloud with out overspending?

A: I like to consider it as being proactive reasonably than reactive. As a substitute of transferring an software to the general public cloud after which asking how it may be optimized, the perfect apply is to think about the person components that impression 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 to your VMs and the volumes they use. To additional optimize your prices, the plan can suggest transferring workloads from on-demand to discounted pricing and buying extra reductions.

The plan calculates prices in line with the billing and worth changes that you’ve got negotiated along with your cloud supplier. Prices embrace 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 software efficiency
  • The price advantage of transferring workloads from on-demand to discounted pricing
  • Reductions you should buy
AWS Cloud Cost Comparison Chart
Cisco Intersight Workload Optimizer gives a comparability of elevate and shift versus optimized workload migration to the general public cloud together with really helpful actions to realize optimized efficiency when transferring to the cloud and on a steady foundation.

You can too see the distinction in dangers (together with efficiency dangers, effectivity alternatives, and compliance dangers) in the event you merely elevate and shift an software to the general public cloud versus in the event you optimize earlier than you progress the applying to the general public cloud. IWO additionally gives a price comparability breakdown between elevate and shift and optimized software migration.

It’s essential to do not forget that optimizing workloads for efficiency and price 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 (similar to shopping for reserved situations, deleting volumes, scaling VMs, and optimizing reserved situations). 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 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 info it gives.

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 means of particular situations.
