What is Hybrid Cloud?
A cloud computing environment that uses a mix of on-premises, private cloud and third-party, public cloud services. Hybrid Cloud allows workloads to move between private and public clouds as computing needs and costs change. Thus, hybrid cloud gives businesses greater flexibility and more data deployment options.
What are the Trends in Hybrid Cloud?
Public cloud services on-premises
In 2015 Amazon Web Services announced Lambda, a serverless platform and a first of its kind that uses event-driven computing constructs (also sometimes referred to as functions as a service or FaaS). 2018 could be the year serverless computing makes its way out of the public cloud and into on-premises data centers. Companies like Microsoft, Red Hat and others are attempting to create serverless functionality in on-premises and hybrid cloud environments. Red Hat, for example, has embraced OpenWhisk, an open source FaaS originally developed by IBM. Microsoft has its own functions platform to bring this born-in-the-cloud technology on-premises.
Another technology being closely watched to potentially come into private and hybrid clouds is machine learning. Public cloud providers seem to be in somewhat of an arms race building out ML and artificial intelligence platforms that customers can integrate into their application-development pipeline.
Cloud Direct Connections
Very few organizations solely use a private or public cloud and in reality, they have workloads in each. Any substantial use of a hybrid cloud can benefit from having an optimized network connection to the cloud. A market of interconnection providers has expanded rapidly in recent years to support this. Companies like Equinix, Digital Realty and QTS offer managed and co-location services that have direct connections to the public cloud, including AWS, Microsoft, Google or many others. As hybrid cloud computing becomes the norm in 2018 and beyond, establishing, managing and optimizing these connections will be a priority.
As business units increasingly consider cloud-based alternatives such as Software-as-a-Service (SaaS) and Infrastructure-as-a-Service (IaaS), the landscape is changing for IT. Cloud is forcing IT’s evolution from that of service provider to that of service broker. Given the choice of managing around cloud technologies or addressing them, IT should embrace cloud options by implementing an efficient and effective hybrid cloud strategy.
Big Data, Internet of Things, and the Mobile Cloud:
Increased adoption of big data, IoT, and mobile devices are major external trends that are converging to provide the perfect catalyst for increased adoption of hybrid cloud services in the medium term. As these major external trends become ubiquitous and the number of organizations laying out policies for bring-your-own-device, use of social media, and sensors increases, there will be an explosion of mobile, structured, and unstructured data. The hybrid cloud will provide an ideal ecosystem and platform for the planning and rapid execution of these major trends.
Microservices is a new paradigm for deploying applications that relies on each tier of an application being its own horizontally scalable layer. The servers in each tier typically have a single job, for example, an authentication service. With microservices, each tier scales out independently and the services become building blocks that can compose more complex services. Composability is a hallmark of cloud native applications, which are driven by application programming interfaces (APIs), even for intercommunication. Composability via APIs is the object-oriented programming of cloud native applications - it allows isolation, scalability, and re-use. Because microservices depend heavily on network-based API calls for communication between services, the components are highly sensitive to latency between services. That typically means all the services need to be in a local or metro network area. This is a key factor driving the adoption of hybrid cloud: the need to maintain a private cloud environment, but a desire to have fast, low-latency connectivity to public cloud resources to take advantage of public cloud as well.
