The cloud era is setting in and settling steadily. The aiding processes, platforms, policies, procedures, practices, and patterns are being framed and firmed up by IT professionals and professors, to tend toward the cloud. The following sections give the necessary details for our esteemed readers.  

The cloud applications, platforms, and infrastructures are gaining immense popularity these days. Cloud applications are of two primary types:

1. Cloud-enabled: The currently running massive and monolithic applications get modernized and migrated to cloud environments to reap the distinct benefits of the cloud paradigm
2. Cloud-native: This is all about designing, developing, debugging, delivering, and deploying applications directly on cloud environments by intrinsically leveraging the non-functional capabilities of cloud environments

The current and conventional applications that are hosted and running on various IT environments are being meticulously modernized and migrated to standardized and multifaceted cloud environments to reap all the originally expressed benefits of cloud paradigm. Besides enabling business-critical, legacy, and monolithic applications to be cloud-ready, there are endeavors for designing, developing, debugging, deploying, and delivering enterprise-class applications in cloud environments, harvesting all of the unique characteristics of cloud infrastructure and platforms. These applications natively absorb the various characteristics of cloud infrastructures and act adaptively. There is microservices architecture (MSA) for designing next-generation enterprise-class applications. MSA is being deftly leveraged to enable massive applications to be partitioned into a collection of decoupled, easily manageable, and fine-grained microservices.

With the decisive adoption of cloud technologies and tools, every component of enterprise IT is being readied to be delivered as a service. The cloud idea has really and rewardingly brought in a stream of innovations, disruptions, and transformations for the IT industry. The days of IT as a Service (ITaaS) will soon become a reality, due to a stream of noteworthy advancements and accomplishments in the cloud space.
