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 present, forward-thinking IT leaders are realizing that composability is not only for purposes. The identical idea can apply to the way in which companies devour cloud companies and assets. 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 all main innovation, it is essential for CIOs to make sure that their organizations are ready to engineer a balanced strategy that permits most advantages whereas holding potential drawbacks in examine.
This text gives steering on how one can take full benefit of modular cloud architectures with out creating undue challenges by explaining the next:
-
What a modular cloud structure entails.
-
Easy methods to plan and implement a modular cloud structure.

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 companies out there on demand. The companies are hosted throughout a number of cloud platforms, and totally different models throughout the enterprise can decide and select amongst particular companies 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 corporation desires to make use of cloud servers hosted on Amazon Elastic Compute Cloud (EC2) to check and deploy purposes. One other staff prefers Azure digital machines, the Azure equal of EC2. A modular cloud structure would make this potential by enabling every staff to make use of its most well-liked 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 companies from totally different cloud platforms. For instance, the event staff 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 potential.
Modular Cloud vs. Hybrid Cloud and Multicloud
At first look, modular cloud could sound like a brand new identify for extra conventional cloud methods — specifically, hybrid and multicloud. Truly, these are distinct ideas:
-
A hybrid cloud structure permits a corporation to combine on-premises or personal cloud options with companies from a number of public cloud suppliers. Nonetheless, this does not essentially imply that the companies are composable or modular within the sense that they’re able to function independently of one another. Nor does a hybrid cloud often present a number of choices of the identical kind of cloud service.
-
A multicloud structure entails the usage of two or extra cloud platforms concurrently. In contrast to modular cloud, nevertheless, multicloud does not often enable for various elements of a corporation to make use of cloud companies from discrete suppliers side-by-side. It often merely signifies that totally different groups use totally different cloud platforms, with every staff relying wholly on whichever platform it chooses.
Briefly, modular, composable cloud architectures present larger alternative and suppleness than both hybrid or multicloud with regard to how a corporation consumes cloud companies.
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:
-
Quicker innovation. When groups can choose whichever cloud companies make most sense for his or her wants, preferences and use circumstances, they will construct and deploy options sooner. As an illustration, quite than having to be taught a brand new cloud service as a result of it is the one one out there inside an enterprise, builders might choose the options they already know nicely.
-
Cloud value optimization. When correctly managed (we’ll say extra about this in a second), a modular cloud helps preserve cloud spending in examine by permitting groups to make use of probably the most cost-efficient options for his or her wants.
-
Freedom from lock-in. The extra liberty that enterprise models possess to select from amongst quite a lot of composable cloud options, the much less seemingly the group is to change 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 degree, the principle problem stemming from a modular cloud structure is that it provides complexity to a corporation’s cloud technique. The extra cloud companies the CIO makes out there, the tougher it turns into to make sure that everyone seems to be utilizing them in a safe, environment friendly, cost-effective manner.
For this reason a pivot towards a modular cloud technique should be accompanied by governance and administration practices that preserve these challenges in examine. Particularly, IT leaders ought to contemplate the next 4 finest practices:
-
Outline clear insurance policies about cloud service adoption: Somewhat than leaving it to enterprise models to resolve totally on their very own which cloud companies to make use of, set up tips laying out which companies 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, resulting from 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 companies from a number of suppliers, counting on every supplier’s native tooling to implement governance and safety guidelines turns into messy quick. A greater strategy 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 monitor cloud spending: Monitoring the prices of cloud companies is crucial for holding prices in examine, irrespective of which cloud structure a corporation makes use of. However it turns into much more very important for companies with a modular cloud technique. Price-tracking ought to make sure that the central IT group is aware of which cloud companies every enterprise unit is utilizing and what these companies value. With this perception, IT leaders can determine and proper value inefficiencies on a enterprise unit-by-unit foundation.
-
Assessment and modify cloud service choices frequently: Cloud platforms are dynamic, which means they’re at all times updating their menu of companies and options. To maintain up with this fixed change, modular cloud methods ought to evolve frequently. IT leaders ought to assessment at present authorised cloud companies to find out whether or not they nonetheless meet compliance, governance, and safety wants. They need to additionally assess any new companies which have come on-line just lately and contemplate 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 wide array of cloud companies effectively and securely, IT leaders could take inspiration from a apply referred to as platform engineering, which has grown in reputation lately. Platform engineering is the institution of authorised IT options {that a} enterprise’s inside customers can entry on a self-service foundation, often through a kind of portal referred to as an inside developer platform.
Traditionally, organizations have used platform engineering primarily to supply software program builders with entry to improvement instruments and environments, to not handle cloud companies. However the identical kind of strategy might assist to streamline entry to modular, composable cloud options. To do that, the IT group selects the cloud companies it desires its groups to have the ability to use, then makes them out there via 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 companies, notably these hosted on totally different platforms (which regularly do not combine with different out-of-the-box as simply as companies supplied by the identical cloud supplier).
With an strategy like this, it turns into sensible to unlock the agility advantages of modular cloud architectures whereas minimizing threat — which is precisely what IT leaders ought to try to do as they search for methods to get much more worth out of the cloud.
