Are you ready for business at the speed of ideas? Do you have answers to questions such as how to connect the next billion devices? Cloud adoption means a profound paradigm shift within IT, bringing you the possibility to transform your business at a pace that cannot be matched with traditional infrastructure alternatives.
Current cloud capabilities also already represent down-to-earth proof points for serious enterprise adoption. But what we call digital industrialization is not easy, just necessary.
Let's explore some aspects of it.
Embrace bimodal IT
If we take Gartner's bimodal IT concept of optimal IT operations for truly digital businesses, there should be a balance between what are called Mode 1 and Mode 2 approaches. Your business must be able to sustain stability and reliability (Mode 1 IT)—to make an analogy, only the IT equivalent of trans-oceanic freighter ships, which require disciplined upfront planning and processes to be performed, can offer the scale to serve entire consumer markets.
On the other hand, organizations must be able to innovate and deliver with agility (Mode 2 IT), much in line with the cloud and DevOps cultures.
In fact, cloud technologies can take both approaches to the next level via holistic automation and programmability.
Get used to seeing resources from a 10,000-foot perspective
We have to bear in mind that cloud resources should be viewed as temporary resources that can be launched and disposed of according to need. This leads to the rise of solutions that do not rely on dedicated resources—and many can feel the ground vanishing from beneath their feet when they consider such solutions seriously.
Cloud resources can now be offered as entire services that interact with one another, hiding all of the underlying complexity via abstraction. In fact, it's important to have a mindset in which you take those cloud services for granted, in order to resist the temptation of going back to designing solutions from a physical perspective. For while it is possible to design solutions in an old-style manner with the cloud, you will not be able to capture their full benefits.
Design solutions for resiliency
One day, even the most precious resource will fail, and you can't let your business be vulnerable to this inevitable event.
It is in the very nature of cloud solutions to be built to endure failures of individual components without disrupting their services. This comes as a consequence of the disposable nature of resources, which creates elasticity.
A remarkable case relates to the Simian Army from Netflix, a collection of services that deliberately causes several kinds of failures in the components of a cloud solution in order to stabilize its operation and achieve a level of resiliency beyond the reach of common casual failures.
Pursue cost optimization
You do not need to incur the costs of dedicated resources if you do not need to rely on such resources. So, when designing your solution, you must actively look for opportunities to immediately free yourself of resources you realize you don't need. With current cloud technologies, you can do this on the fly.
Today, the level of granularity of compute services has reached the precision of milliseconds for code execution. Therefore, you practically do not pay for any idle time.
Datacenter consolidation and innovation
Transforming datacenters with more-efficient technologies is not a matter of just moving each individual application to a virtualized environment. Comprehensive analysis has to be carried on to evaluate the entire ecosystem of services according to business criticality, service interdependency, business continuity, and disaster recovery requirements before reaching a coherent transformation plan. Professional approaches employ best practices, methodologies, and automated tools for discovery and analysis.
Depending on the conclusions of the analysis, not every service will be subject to re-architecting for the cloud. Some services will undergo a lift-and-shift strategy, which does not prevent the enterprise from being innovative. After all, what matters most for the cloud is the precedence of collectivity over individuality.
