As cloud computing adoption increases, many enterprises are not developing a full vision for their cloud computing efforts. Most of the projects being deployed in the cloud are more for testing and proof of concept than actual production, but there are projects that show such success in the cloud that they are left there permanently. I am not one to discourage enterprises from 'testing the waters' of the cloud in whatever fashion they deem proper, but I do highly recommend that an overall 'cloud computing vision' be developed when the cloud is to be officially adopted as a production resource.
As noted in a recent InfoWorld blog on the topic, this type of unstructured or experimental method of cloud adoption will probably continue for the near future. This scenario mainly applies to the public cloud, but it will soon migrate over to the private and hybrid cloud infrastructures. In limited quantities, this is a manageable scenario. When the speed and frequency of cloud migration projects begin to rise, this creates a familiar and unpleasant situation.
When server virtualization first began to take hold in the data centers of the world, the technology promised so much that IT completely ignored a key facet of any large scale deployment - management. It was so easy to build and deploy virtual machines that most organizations failed to put constraints and processes for virtual server deployments. This created the issue that many organizations are now facing - VM sprawl. Many vendors have risen to combat the growing problem of server sprawl, but this illustrates what is set to happen in the cloud computing world.
As these small projects take to the cloud, most organizations are not putting the processes in place to contain and manage the deployments. Organizations are more concerned with security and compliance than they are of management. Over time, these deployments will grow in number and end up a tangled mess of systems that do not work with each other well. They will be a nightmare to manage and the business value that was supposed to result from the shift to cloud computing will not pan out. Fortunately, this can all be avoided if enterprises take the time to develop a concise yet thorough plan for cloud computing adoption. This strategy must be communicated to everyone involved from the top business people to the IT staff.
A cloud computing vision defines the business goals of the company and illustrates how cloud computing will serve to deliver on those goals. The vision must have a long term plan in which the path to full cloud adoption is laid out and logical steps are identified in the process. The vision should highlight issues such as security, compliance, governance, provisioning, change management and departure from the cloud (should this be necessary). The vision should give the 'big picture' of how an organization will approach cloud computing. From the vision, the various project managers and technical staff can develop the smaller solutions that will work toward that common idea.
The cloud computing vision will help to deliver on the promise of business value by ensuring that projects are cohesive in addition to being less complex and less expensive. The vision will also expedite the process of moving from a CAPEX heavy business model to a lean OPEX-centric model. The vision will lower the risks to cloud computing adoption by offering a well defined plan and identifying potential challenges ahead of time. Having a cloud computing vision will increase the chance that an organization's cloud computing efforts are successful.
[session] Design and Deliver Microservices By @OnQuality | @DevOpsSummit #Cloud #DevOps #Microservices
For organizations that have amassed large sums of software complexity, taking a microservices approach is the first step toward DevOps and continuous improvement / development. Integrating system-level analysis with microservices makes it easier to change and add functionality to applications at any time without the increase of risk. Before you start big transformation projects or a cloud migration, make sure these changes won’t take down your entire organization.

Updating DevOps to the latest production data slows down your development cycle. Probably it is due to slow, inefficient conventional storage and associated copy data management practices. In his session at @DevOpsSummit at 20th Cloud Expo, Dhiraj Sehgal, in Product and Solution at Tintri, will talk about DevOps and cloud-focused storage to update hundreds of child VMs (different flavors) with updates from a master VM in minutes, saving hours or even days in each development cycle. He will also...

Thanks to Docker, it becomes very easy to leverage containers to build, ship, and run any Linux application on any kind of infrastructure. Docker is particularly helpful for microservice architectures because their successful implementation relies on a fast, efficient deployment mechanism – which is precisely one of the features of Docker. Microservice architectures are therefore becoming more popular, and are increasingly seen as an interesting option even for smaller projects, instead of being...

Microservices (μServices) are a fascinating evolution of the Distributed Object Computing (DOC) paradigm. Initial design of DOC attempted to solve the problem of simplifying developing complex distributed applications by applying object-oriented design principles to disparate components operating across networked infrastructure. In this model, DOC “hid” the complexity of making this work from the developer regardless of the deployment architecture through the use of complex frameworks, such as C...

In today's enterprise, digital transformation represents organizational change even more so than technology change, as customer preferences and behavior drive end-to-end transformation across lines of business as well as IT. To capitalize on the ubiquitous disruption driving this transformation, companies must be able to innovate at an increasingly rapid pace. Traditional approaches for driving innovation are now woefully inadequate for keeping up with the breadth of disruption and change facing...

When building large, cloud-based applications that operate at a high scale, it’s important to maintain a high availability and resilience to failures. In order to do that, you must be tolerant of failures, even in light of failures in other areas of your application. “Fly two mistakes high” is an old adage in the radio control airplane hobby. It means, fly high enough so that if you make a mistake, you can continue flying with room to still make mistakes. In his session at 18th Cloud Expo, Lee A...

As we enter the final week before the 19th International Cloud Expo | @ThingsExpo in Santa Clara, CA, it's time for me to reflect on six big topics that will be important during the show. Hybrid Cloud: This general-purpose term seems to provide a comfort zone for many enterprise IT managers. It sounds reassuring to be able to work with one of the major public-cloud providers like AWS or Microsoft Azure while still maintaining an on-site presence.

As software becomes more and more complex, we, as software developers, have been splitting up our code into smaller and smaller components. This is also true for the environment in which we run our code: going from bare metal, to VMs to the modern-day Cloud Native world of containers, schedulers and micro services. While we have figured out how to run containerized applications in the cloud using schedulers, we've yet to come up with a good solution to bridge the gap between getting your contain...

Thanks to Docker and the DevOps revolution, microservices have emerged as the new way to build and deploy applications — and there are plenty of great reasons to embrace the microservices trend. If you are going to adopt microservices, you also have to understand that microservice architectures have many moving parts. When it comes to incident management, this presents an important difference between microservices and monolithic architectures. More moving parts mean more complexity to monitor an...

You often hear the two titles of "DevOps" and "Immutable Infrastructure" used independently. In his session at DevOps Summit, John Willis, Technical Evangelist for Docker, covered the union between the two topics and why this is important. He provided an overview of Immutable Infrastructure then showed how an Immutable Continuous Delivery pipeline can be applied as a best practice for "DevOps." He ended the session with some interesting case study examples.
