Virtualization is the Cloud

…and so is elastic scalability, metered billing, resource pooling, hardware abstraction and many other concepts.

For me there is too much discussion over what a cloud should and should not be.

“Cloud is not virtualization” sounds like a billboard on the US101 in Silicon valley. Wait! It is a billboard on the 101 thanks to Microsoft.

Can’t we be inclusive. Can’t everyone just get along :)

It is after all, predominantly marketing term that has attached some defacto guiding principles. Not a standard to be defined. You cannot be a zealot in the definition.

There are so many blog posts (and here) trying to define the cloud with a different spin, and trying to define its economics. Haven’t we done this to death? I know the biggest barrier to cloud architecture adoption is knowledge, but the information is out there already, adding more information just makes it confusing.

I think there should be more focus on the application and not the cloud. Having scalable infrastructure very rarely results in scalable workload, in fact, the opposite. It reveals the real problems, architecturally and technically within an application. In addition, infrastructure utilization/latency does not necessarily determine the trigger for scale management. Self-service is only valuable to a cross-section of organizations, but speed of provisioning is much more widely needed. Metered usage makes less sense to many companies, but elasticity is of great value.

Shift the focus on how to make use of it, not its definition. How do you determine what applications should be deployed in a cloud based architecture, and what level of “cloudiness” you need to deliver business value. Remember, there is no way you are getting a project approved to spend any money without some link to business value.

Krishnan, Principal Architect at REAN Cloud, discussed how they built...
Most technology leaders, contemporary and from the hardware era, are reshaping their businesses to do software. They hope to capture value from emerging technologies such as IoT, SDN, and AI. Ultimately, irrespective of the vertical, it is about deriving value from independent software applications participating in an ecosystem as one comprehensive solution. In his session at @ThingsExpo, Kausik Sridhar, founder and CTO of Pulzze Systems, discussed how given the magnitude of today's application ...
The “Digital Era” is forcing us to engage with new methods to build, operate and maintain applications. This transformation also implies an evolution to more and more intelligent applications to better engage with the customers, while creating significant market differentiators. In both cases, the cloud has become a key enabler to embrace this digital revolution. So, moving to the cloud is no longer the question; the new questions are HOW and WHEN. To make this equation even more complex, most ...

The past few years have brought a sea change in the way applications are architected, developed, and consumed—increasing both the complexity of testing and the business impact of software failures. How can software testing professionals keep pace with modern application delivery, given the trends that impact both architectures (cloud, microservices, and APIs) and processes (DevOps, agile, and continuous delivery)? This is where continuous testing comes in. D
Modern software design has fundamentally changed how we manage applications, causing many to turn to containers as the new virtual machine for resource management. As container adoption grows beyond stateless applications to stateful workloads, the need for persistent storage is foundational - something customers routinely cite as a top pain point. In his session at @DevOpsSummit at 21st Cloud Expo, Bill Borsari, Head of Systems Engineering at Datera, explored how organizations can reap the bene...

In a recent survey, Sumo Logic surveyed 1,500 customers who employ cloud services such as Amazon Web Services (AWS), Microsoft Azure, and Google Cloud Platform (GCP). According to the survey, a quarter of the respondents have already deployed Docker containers and nearly as many (23 percent) are employing the AWS Lambda serverless computing framework. It’s clear: serverless is here to stay. The adoption does come with some needed changes, within both application development and operations. Tha...
