When Workloads Are in the Wrong Place

By some estimates, as many as 82% of enterprises have adopted hybrid multiclouds, which combine private and public cloud IT resources. Enterprises have deployed mixed-cloud infrastructures for a variety of reasons, and the overriding one may very well be happenstance.

In a podcast earlier this year, David Linthicum, chief cloud strategy officer at Deloitte Consulting, told eWeek that the pandemic and shadow IT have resulted in many organizations running multiple clouds by accident. 

“This has put them in situations they didn’t necessarily plan for. Multicloud is hard, complex, with lots of moving parts,” Linthicum said.

And that can leave cloud workloads unoptimized.

Cost Misconception?

In companies that have implemented hybrid multicloud by design, a frequently mentioned motivation is a desire to run IT workloads as inexpensively as possible, which many believe requires avoiding lock-in with any one cloud provider.

Yet there’s a catch, according to Linthicum.

“Multicloud gives you choice, but it doesn’t necessarily solve the problem of vendor lock-in,” he said. “Once you leverage the features of a given provider’s service, you’re kind of stuck unless you want to rewrite or refactor those systems to be native on other cloud provider platforms.” That can be costly, time-consuming and risky.

He did acknowledge, however, the emergence of “promising AIOps tools…that can look at multiple clouds and deal with multiple services through abstraction and automation.” Those tools assist in liberating applications from cloud-native trappings, helping avoid lock-in.

Linthicum estimated that by the end of 2022 and into 2023, “enterprises will refocus on cross-cloud rather than optimizing for one cloud. That means [they’ll need] fewer people and a single base of talent” rather than multiple independent cloud-native skillsets.

Top Optimization Variables

Cost is an important variable to consider when optimizing workloads. Cost-optimizing the placement of an application, for example, may involve using a public cloud service early on and later moving it to a more affordable private infrastructure, said Harsha Kotikela, director of product and solution marketing at Nutanix.

“For example, when organizations are building a new application, they often prefer to rent out infrastructure from the [public] cloud, instead of building new capacity in their data center, to see how that application is received,” he said. 

“Once it’s done and they see how the application is received, they might move it back on-prem depending on their existing capacity or data locality and other factors. Public cloud is good for flexibility, but it could cost more.”

Cost is just one optimization factor, however. Comprehensive cloud optimization requires continually balancing per-workload support costs with application performance and data sovereignty considerations, said Lee Caswell, senior vice president of product and solutions marketing at Nutanix. Business continuity is another factor. All increasingly require tools that can provide consistent experience  across private and public clouds to provide visibility, alerts and integration.

Caswell explained that performance is largely driven by how long it takes to access data. Access can be accelerated using hyperconverged infrastructure (HCI), which collocates compute power and data storage for minimal latency, he said. He added that it also helps to adopt public cloud services with infrastructure in the country(ies) where enterprises serve employees and customers to reduce distance-induced delay.

Data sovereignty covers security, governance, and regulatory compliance. “It involves who owns my data, who can subpoena my data, and knowing exactly where my data is,” Caswell explained.

Persistent Workload Placement

Cost, performance, security/compliance, and business continuity optimization varies by application, industry standards, government regulation, and corporate philosophy. These components are also fluid: as time marches on, cloud service options, pricing, and regulations change. The dynamic nature of the digital economy, then, favors regular reevaluation of what’s running where over “set-and-forget” hybrid multicloud management approaches.

In fact, Gartner predicts that by 2027, 85% of workload placements made through 2022 will no longer be optimal, because many enterprises using multiple cloud platforms will not have figured out how to stay on top of change management.

Rather than waiting for user complaints about application performance or a compliance violation to rear its head, having a hybrid multicloud strategy can put IT teams ahead of the game, according to Kotekela. It allows them to inventory, assess and move applications based on cloud services, skillsets, service-level agreements (SLAs) and more on an ongoing basis.  

5 Guiding Steps to Cloud Optimization

Combining a hybrid multicloud blueprint with intelligent tools that simplify cross-cloud data integration, ease application mobility and alert you to cloud pricing changes helps avoid cloud-to-workload misalignment that can create unnecessary expenses, degrade performance and compromise security.

Below are five basic steps, culled from a variety of industry experts and reports, to keep applications and workloads optimized over time.

1. Create a cloud framework. Build a map of your existing private/public cloud environment. Include all the workloads you know about and can discover with cloud visibility tools, where they currently run, their performance requirements, any service-level agreements (SLAs) in place to support them, and alternative potential cloud placement options. Add an inventory of all the different cloud services you use, how you connect to them, if and how they connect to each other, and the departments that use each service. Document all the cloud skillsets available in the organization. This framework creates a foundation for managing cloud assets going forward.

2. Identify integration needs. With a bird's-eye view of the whole cloud environment, specify how individual clouds currently share data or are likely to do so in the future. What integration tools and technologies do you need to connect applications, systems, data repositories, and IT environments and enable the real-time exchange of data and processes?

For example, Nutanix Cloud Clusters (NC2) is a cloud-agnostic toolset that eases hybrid multicloud integration issues. It replicates the Nutanix cloud platform enterprises use to build and manage their on-premises private clouds in public cloud environments. Natively integrated with public cloud providers, NC2 hides the differences and complexities of these platforms from IT operators using an abstraction layer that makes mixed Nutanix private clouds and public clouds appear as a consistent single environment. In this way, it enables application mobility across clouds without retooling, code changes or new skill sets, helping minimize cost and risk. It also enables consistent cloud management, security policy setting and enforcement, and cost optimization across the mixed hybrid multicloud using complementary applications that work on top of NC2.

3. Establish a platform-agnostic cloud-deployment automation strategy. Identify where most time is spent and what most needs automation. If plans call for using a wide variety of cloud services, it can be beneficial to create standardized rules for deploying different cloud environments that easily translate into automated configuration rules.

4. Evaluate IT resource requirements, especially networking. This includes processing power, data storage capacity, and the network infrastructure that connects all the cloud components. Consider, for example, cumulative latency that builds up among connections across multiple cloud infrastructures and the potential aggregate effect it might have on application performance. If it’s prohibitive to SLAs, consider direct cloud interconnection services between your private and public cloud(s), which bypass the public Internet to decrease latency and improve performance.

5. Deploy cross-cloud tools for optimizing cost, business continuity and staying ahead of security complexity. These are increasingly available from both Nutanix and third parties. NC2, for example, supports Nutanix Cost Governance for automatically tracking costs across all private/public cloud instances and discovering more cost-effective options. Security managers such as Nutanix Flow Security Central provide you with a common dashboard for managing security across the whole hybrid multicloud without having to deal with each native-cloud security system separately. And native disaster recovery (DR) capabilities in NC2 support creating custom, per-application protection levels across multiple clouds and options for "elastic" and "hibernating" DR that support dynamic business continuity requirements while helping you manage costs.

Prepare for Growth

Businesses running hybrid multicloud environments may have some foundational strategies in place for managing them. As the number and variety of cloud services they use grow, they need to be prepared that their environments will become more complex.

As Deloitte’s Linthicum noted in an August article for Infoworld, complexity is a byproduct of heterogeneity, which in turn results from businesses wanting to provision best-of-breed cloud services.

While “a natural progression of the expansion of cloud computing,” he wrote, it results in most enterprises increasing the number of services they use, and more services naturally result in added cost.

Managing cost and complexity requires optimizing all workloads so that they meet business needs consistently and reliably over time at the best possible price point. Enterprises should plan ahead by creating a dynamic, evolving framework that takes advantage of abstraction and automation and the latest cross-cloud tools that transcend cloud-native platforms as they become available.
