Services in a Cloud Computing Environment

Expect to see some interesting things in the future around services for the virtualized data center

Omar Sultan's Blog

Once we cut through the cloud-hype and start looking at the practicalities of implementing things like workload portability, I think the lessons of the past will re-assert themselves, this time with things like security and L4-7 services.

Quite a few years ago, when we we positioning the concept of the intelligent network, we had a slide that showed how features moved from servers or dedicated hardware to the the network over time. The trigger was usually when a service, say name resolution, became broadly used. At that point, it was seldom workable to have that service delivered by a place in the network--it needed to be ubiquitous...and highly available...and scaleable...and manageable...and usually ended up as a network service.

Reading a recent post by the ever fearless Christofer Hoff and the related Twitter exchange got me thinking about this again. Once we cut through the cloud-hype and start looking at the practicalities of implementing things like workload portability, I think the lessons of the past will re-assert themselves, this time with things like security and L4-7 services. There was a time when security=firewall, in essence, security was associated with a specific place in your network. Now, to be effective, security needs to be pervasively deployed and deliver security services that ubiquitous and consistent--no matter where a workload runs (my desktop, my data center, someone else’s data center) the security policy must be consistently implemented.

In short, models that depend on services such as security or load-balancing being associated with a specific place in the the network or a specific piece of infrastructure will not survive the transition. We need to be able to implement services wherever they are needed--the ability to provide security services to a given workload cannot be constrained by whether that workload happens to be running on a server that happens to be plugged into a firewall--it would be like saying you can only call certain area codes from certain certain extensions in your house--”Oh, you want to call New York? You’ll have to use the phone in the guest bedroom...”

For us, this is in our DNA--you plug into the network, you get access to all its goodness. As an example, our SAN solutions are built upon the concept of and intelligent fabric, where critical services are a function of the network,not a specific box. This means that I don’t have to worry about a server dying and taking my VSAN routing with it. It also means my capacity and performance automatically scale-up and scale-down with the number of switches in the network.

Unified fabric is an extension of this concept: plug into a unified fabric and you automatically have access to all your storage resources--no HBAs, no fiber runs, no fabric switches--access to storage is no longer a function of having specific infrastructure deployed. VN-Link and the Nexus 1000V are also a logical extension of this concept: no matter where a workload (VM) ends up running, its security policy will stay with it, so application of security policy is no longer a function of having a workload running in a specific location.

As you may guess we are continuing to expand on this concept, so expect to see some interesting things in the future around services for the virtualized data center.

To get the most out of their data, successful companies are not focusing on queries and data lakes, they are actively integrating analytics into their operations with a data-first application development approach. Real-time adjustments to improve revenues, reduce costs, or mitigate risk rely on applications that minimize latency on a variety of data sources. In his session at @BigDataExpo, Jack Norris, Senior Vice President, Data and Applications at MapR Technologies, reviewed best practices to ...
DevOps promotes continuous improvement through a culture of collaboration. But in real terms, how do you: Integrate activities across diverse teams and services? Make objective decisions with system-wide visibility? Use feedback loops to enable learning and improvement? With technology insights and real-world examples, in his general session at @DevOpsSummit, at 21st Cloud Expo, Andi Mann, Chief Technology Advocate at Splunk, explored how leading organizations use data-driven DevOps to close th...
"Digital transformation - what we knew about it in the past has been redefined. Automation is going to play such a huge role in that because the culture, the technology, and the business operations are being shifted now," stated Brian Boeggeman, VP of Alliances & Partnerships at Ayehu, in this SYS-CON.tv interview at 21st Cloud Expo, held Oct 31 – Nov 2, 2017, at the Santa Clara Convention Center in Santa Clara, CA.
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

Digital Transformation (DX) is not a "one-size-fits all" strategy. Each organization needs to develop its own unique, long-term DX plan. It must do so by realizing that we now live in a data-driven age, and that technologies such as Cloud Computing, Big Data, the IoT, Cognitive Computing, and Blockchain are only tools. In her general session at 21st Cloud Expo, Rebecca Wanta explained how the strategy must focus on DX and include a commitment from top management to create great IT jobs, monitor ...
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).

A strange thing is happening along the way to the Internet of Things, namely far too many devices to work with and manage. It has become clear that we'll need much higher efficiency user experiences that can allow us to more easily and scalably work with the thousands of devices that will soon be in each of our lives. Enter the conversational interface revolution, combining bots we can literally talk with, gesture to, and even direct with our thoughts, with embedded artificial intelligence, whic...
You know you need the cloud, but you're hesitant to simply dump everything at Amazon since you know that not all workloads are suitable for cloud. You know that you want the kind of ease of use and scalability that you get with public cloud, but your applications are architected in a way that makes the public cloud a non-starter. You're looking at private cloud solutions based on hyperconverged infrastructure, but you're concerned with the limits inherent in those technologies. What do you do?
