How DevOps Should Use DBaaS (Database-as-a-Service) To Optimize Their Application Development

This post was written by Wendy Dessler of The Blog Frog.

Database-as-a-Service (DBaaS) is quickly gaining in popularity across the tech world. These software platform solutions helps users easily manage their database operations without having to really understand any of the abstractions. This allows developers, DBA’s and DevOps engineers to quickly automate their backups, create new SQL and NoSQL clusters, and monitor the performance of their databases for their application without requiring any internal database expertise.

DBaaS falls under the umbrella of Platform-as-a-Service (PaaS) where the platform itself is actually a database or several databases. This is a great choice for DevOps in particular because it allows for more developer agility, productivity, and also security.

Flexibility and scalability are becoming more important in the world of DevOps and technology in general, and we all know how fast this world moves. Businesses need new ways to keep up with the competition, and developers are looking for an easy, self-service model for managing their databases in order to optimize their app development. Let’s break down the individual benefits so you can decide if DBaaS is right for your DevOps team.

Whither Network Engineering? (Part 3)

In the previous two parts of this series, I have looked at the reasons I think the networking ecosystem is bound to change and why I think disaggregation is going to play a major role in that change. If I am right about the changes happening, what will become of network engineers? The bifurcation of knowledge, combined with the kinds of networks and companies noted in the previous posts in this series, point the way. There will, I think, be three distinct careers where the current “network engineer” currently exists on the operational side:

  1. Moving up the stack, towards business, the more management role. This will be captured primarily by the companies that operate in market verticals deep and narrow enough to survive without a strong focus on data, and hence can survive a transition to black box, fully integrated solutions. This position will largely be focused on deploying, integrating, and automating vertically integrated, vendor-driven systems and managing vendor relationships.
  2. Moving up the stack, towards software and business, the disaggregated network engineering role (I don’t have a better name for this presently). This will be in support of companies that value data to the point of focusing on its management Continue reading

Born in 1994, about the same time Tim Berners-Lee founded the World Wide Web Consortium and a commercialized Internet started to take form, the Internet has inextricably shaped my life and career.

At 16 years old, I got my first job at an Internet café. I had taught myself to type, and that was all I needed to teach people that they couldn’t just guess a password if they had not already set up an email account. Many young people in developing nations are still grappling to learn the computer (it’s Continue reading

io_submit: The epoll alternative you’ve never heard about

io_submit: The epoll alternative you've never heard about

My curiosity was piqued by an LWN article about IOCB_CMD_POLL - A new kernel polling interface. It discusses an addition of a new polling mechanism to Linux AIO API, which was merged in 4.18 kernel. The whole idea is rather intriguing. The author of the patch is proposing to use the Linux AIO API with things like network sockets.

Hold on. The Linux AIO is designed for, well, Asynchronous disk IO! Disk files are not the same thing as network sockets! Is it even possible to use the Linux AIO API with network sockets in the first place?

The answer turns out to be a strong YES! In this article I'll explain how to use the strengths of Linux AIO API to write better and faster network servers.

But before we start, what is Linux AIO anyway?

Introduction to Linux AIO

Linux AIO exposes asynchronous disk IO to userspace software.

Historically on Linux, all disk operations were blocking. Whether you did open(), read(), write() or fsync(), you could be sure your thread would stall if the needed data and meta-data was not ready in disk cache. This usually isn't Continue reading

Poor data-center configuration leads to severe waste problem

All of the monstrous data centers popping up globally are having multiple negative impacts on the planet, the EPA notes.First, there is the obvious effect, power consumption. Data centers account for 3 percent of the global electricity supply and consume more power than the entire United Kingdom.But beyond that is the waste caused by disposal. With Amazon and the like deploying more than a million physical servers per year globally, the old server equipment they replace have to go somewhere. The same goes for your old servers.[ Read also: Chip-cooling breakthrough will reduce data-center power costs | Get regularly scheduled insights: Sign up for Network World newsletters ] E-waste 70 percent of toxic waste The EPA estimates e-waste, disposed electronics, now accounts for 2 percent of all solid waste and 70 percent of toxic waste, thanks to the use of chemicals such as lead, mercury, cadmium and beryllium, as well as hazardous chemicals such as brominated flame retardants. A lot of that is old servers and components.To read this article in full, please click here

Why does Mellanox have four potential suitors?

It looks like Microsoft is looking to give itself the gift of networking in the form of an acquisition — Mellanox. But it may have to get in line.An Israeli financial publication called TheMarker reports that Microsoft not only has an interest in acquiring the network chip maker, but it also has reportedly engaged Goldman Sachs to handle negotiations. The rumors first popped up before Christmas, and understandably there has been little activity since.But Microsoft may not be the only vendor looking to grab Mellanox. Data Centre Dynamics in the U.K. reported last month that three other firms — Xilinx, Intel, and Broadcom — could also be interested in acquiring the company. As far back as October, CNBC was reporting that Mellanox was looking for a buyer.To read this article in full, please click here
