Among the many most sweeping IT improvements of the previous decade has been the shift towards modular, composable software program architectures, comparable to people who energy microservices purposes. By breaking software program into discrete items that organizations might develop and deploy independently, modular architectures boosted effectivity and reliability.
At this time, forward-thinking IT leaders are realizing that composability is not only for purposes. The identical idea can apply to the best way companies devour cloud providers and sources. A modular, composable cloud structure injects one other layer of effectivity and scalability into IT operations.
Nonetheless, composable cloud architectures additionally introduce challenges in areas like compliance, governance, and safety. As with every main innovation, it is essential for CIOs to make sure that their organizations are ready to engineer a balanced method that permits most advantages whereas protecting potential drawbacks in test.
This text supplies steerage on the best way to take full benefit of modular cloud architectures with out creating undue challenges by explaining the next:
-
What a modular cloud structure entails.
-
The way to plan and implement a modular cloud structure.Â

Greatest practices for maximizing the enterprise agility {that a} modular cloud technique unlocks.
What’s a Modular Cloud Structure?
A modular cloud structure is one which makes quite a lot of discrete cloud providers accessible on demand. The providers are hosted throughout a number of cloud platforms, and completely different items throughout the enterprise can decide and select amongst particular providers to satisfy their wants.
For example of a modular cloud structure in apply, think about a state of affairs the place one of many software program improvement groups inside a company needs to make use of cloud servers hosted on Amazon Elastic Compute Cloud (EC2) to check and deploy purposes. One other workforce prefers Azure digital machines, the Azure equal of EC2. A modular cloud structure would make this doable by enabling every workforce to make use of its most popular cloud server service, versus requiring everybody to deploy the identical service as a result of the group helps just one.
Going additional, modular clouds additionally allow the side-by-side use of providers from completely different cloud platforms. For instance, the event workforce that makes use of EC2 cloud server situations to check and deploy apps may wish to use Azure Pipelines (a hosted CI/CD service within the Azure cloud) for the event course of. Beneath a modular cloud structure, this may be doable.
Modular Cloud vs. Hybrid Cloud and Multicloud
At first look, modular cloud might sound like a brand new identify for extra conventional cloud methods — specifically, hybrid and multicloud. Really, these are distinct ideas:
-
A hybrid cloud structure permits a company to combine on-premises or non-public cloud options with providers from a number of public cloud suppliers. Nonetheless, this does not essentially imply that the providers are composable or modular within the sense that they can function independently of one another. Nor does a hybrid cloud often present a number of picks of the identical sort of cloud service.
-
A multicloud structure entails the usage of two or extra cloud platforms concurrently. Not like modular cloud, nonetheless, multicloud would not often permit for various elements of a company to make use of cloud providers from discrete suppliers side-by-side. It often merely implies that completely different groups use completely different cloud platforms, with every workforce relying wholly on whichever platform it chooses.
Briefly, modular, composable cloud architectures present better alternative and suppleness than both hybrid or multicloud with regard to how a company consumes cloud providers.
The Enterprise Advantages of Modular Clouds
The selection and suppleness that come up from a modular, composable cloud results in key enterprise advantages, together with the next:Â
-
Sooner innovation. When groups can choose whichever cloud providers make most sense for his or her wants, preferences and use circumstances, they will construct and deploy options sooner. As an illustration, relatively than having to be taught a brand new cloud service as a result of it is the one one accessible inside an enterprise, builders might choose the options they already know nicely.
-
Cloud price optimization. When correctly managed (we’ll say extra about this in a second), a modular cloud helps maintain cloud spending in test by permitting groups to make use of essentially the most cost-efficient options for his or her wants.
-
Freedom from lock-in. The extra liberty that enterprise items possess to select from amongst quite a lot of composable cloud options, the much less doubtless the group is to develop into depending on any single vendor or service.
Managing the Challenges of Modular Cloud Architectures
With these advantages come some distinct challenges.
At a excessive stage, the principle problem stemming from a modular cloud structure is that it provides complexity to a company’s cloud technique. The extra cloud providers the CIO makes accessible, the more durable it turns into to make sure that everyone seems to be utilizing them in a safe, environment friendly, cost-effective means.
Because of this a pivot towards a modular cloud technique have to be accompanied by governance and administration practices that maintain these challenges in test. Particularly, IT leaders ought to take into account the next 4 greatest practices:
-
Outline clear insurance policies about cloud service adoption: Quite than leaving it to enterprise items to resolve fully on their very own which cloud providers to make use of, set up tips laying out which providers are acceptable for which use circumstances. As an illustration, the group may deem {that a} sure cloud service could also be used for internet hosting purposes that don’t handle delicate information, whereas additionally stating that, as a result of compliance or safety dangers, the identical service cannot be used for purposes that deal with monetary information or PII.
-
Use cloud-agnostic tooling for governance and safety. When a enterprise makes use of quite a lot of cloud providers from a number of suppliers, counting on every supplier’s native tooling to implement governance and safety guidelines turns into messy quick. A greater method is to make use of third-party options (comparable to infrastructure as code instruments that work throughout clouds) to outline and implement governance and safety insurance policies.
-
Granularly observe cloud spending: Monitoring the prices of cloud providers is important for protecting prices in test, irrespective of which cloud structure a company makes use of. Nevertheless it turns into much more important for companies with a modular cloud technique. Price-tracking ought to make sure that the central IT group is aware of which cloud providers every enterprise unit is utilizing and what these providers price. With this perception, IT leaders can establish and proper price inefficiencies on a enterprise unit-by-unit foundation.
-
Evaluate and regulate cloud service choices recurrently: Cloud platforms are dynamic, that means they’re all the time updating their menu of providers and options. To maintain up with this fixed change, modular cloud methods ought to evolve recurrently. IT leaders ought to assessment presently authorised cloud providers to find out whether or not they nonetheless meet compliance, governance, and safety wants. They need to additionally assess any new providers which have come on-line not too long ago and take into account whether or not including them to the enterprise’s suite of cloud options would profit the group.
Taking a Cue from Platform Engineering
As they work to make sure that the enterprise can devour a big selection of cloud providers effectively and securely, IT leaders might take inspiration from a apply often called platform engineering, which has grown in reputation in recent times. Platform engineering is the institution of authorised IT options {that a} enterprise’s inside customers can entry on a self-service foundation, often by way of a sort of portal often called an inside developer platform.
Traditionally, organizations have used platform engineering primarily to offer software program builders with entry to improvement instruments and environments, to not handle cloud providers. However the identical form of method might assist to streamline entry to modular, composable cloud options. To do that, the IT group selects the cloud providers it needs its groups to have the ability to use, then makes them accessible by way of enterprise cloud accounts utilizing preconfigured settings that conform with governance, compliance, and safety wants. The built-in configurations also can assist to make sure interoperability between cloud providers, significantly these hosted on completely different platforms (which frequently do not combine with different out-of-the-box as simply as providers provided by the identical cloud supplier).
With an method like this, it turns into sensible to unlock the agility advantages of modular cloud architectures whereas minimizing threat — which is strictly what IT leaders ought to attempt to do as they search for methods to get much more worth out of the cloud.
