Microservices Gone Wild – Tech Dive Part 1

Tech Dive - Microservices

I’ve heard a lot of noise about microservices in the last couple of years, perhaps most notably when I attended ONUG in Spring 2015 and Adrian Cockcroft from Battery Ventures (previously from Netflix) was pushing the idea of building applications using container-based microservices very convincingly. In this short series of posts, I’ll look at what microservices are, why you might want them (particularly in containers) and — because it would be no fun if this was all just theory — I’ll run through a demonstration where I take a simple monolithic application and successfully break it out into containerized microservices. I’ll share the code I use because I just know you’ll enjoy playing along at home.

Monolithic Applications

In order to consider the benefits of microservices it’s important first to get some context by looking at what is arguably the polar opposite, the monolithic application. I should preface this by saying that defining what constitutes a monolithic application can be a rather nuanced task, depending on the perspective from which one looks. For my purposes though, a monolithic application is typically one where the entire application is delivered in a single release. Even if the application is logically deployed across Continue reading

HP’s Elite X3 smartphone with Windows 10 will ship this month for $699

Not many are using smartphones with Microsoft's Windows 10 Mobile, but HP's flagship Elite X3 -- which ships this month -- could boost the OS's sagging fortunes. The premium smartphone will be priced starting at US$699 in the U.S. It feels more like a phablet, but HP believes it could also be a PC in a pinch with its top-line mobile processor, OS and innovative accessories. HP first announced the Elite X3 at the Mobile World Congress trade show in February. It has a 5.96-inch AMOLED screen that can display images at a 2560 x 1440 pixel resolution, matching top smartphones like Samsung's Galaxy S7 and LG's G5. The rugged screen has Gorilla Glass 4 technology.To read this article in full or to leave a comment, please click here

NSF and GR on Nexus 5000

NSF and GR are two features in Layer 3 network elements (NEs) that allows two adjacent elements to work together when one of them undergoes a control plane switchover or control plane restart.

The benefit is that when a control plane switchover/restart occurs, the impact to network traffic is kept to a minimum and in most cases, to zero.

NSF

  • Non-Stop Forwarding
  • When a control plane protocol such as BGP, OSPF, or EIGRP restarts and neighbors/adjacencies are reset, NSF will allow the data plane to hold onto the routes that were learned via that control plane protocol and continue to forward traffic while the neighbors/adjacencies are re-established.
  • Control plane restarts occur when you have a router or switch with dual route processors or supervisor engines and there is a switchover from the active to the hot standby. When the newly active RP/sup takes over, it has to re-establish neighbors/adjacencies because that information is not part of the synchronization that occurs between the two RPs/sups.
  • NSF keeps traffic moving — without the need to reroute — while the switchover is happening.
  • NSF happens locally, all within the network element where the switchover is happening.

Facebook details its 2016 open source accomplishments

Facebook added 54 new projects to its open-source initiative during the last six months. The company is on a mission to open source its code for software and hardware to encourage ongoing development from outside companies and engineers. "We build tools that enable engineers to work more easily across platforms, automate testing to catch problems sooner, and help improve the overall performance of our products," wrote Christine Abernathy, a developer advocate with Facebook's open source team, in a blog post. "We know from experience that collaborating with the open source community surfaces new ideas and solutions to the challenges that we face." To read this article in full or to leave a comment, please click here

Microsoft disavows 1B-or-bust goal for Windows 10

Microsoft today acknowledged that it would not make its self-imposed goal of putting Windows 10 on 1 billion devices by mid-2018. "We're pleased with our progress to date, but due to the focusing of our phone hardware business, it will take longer than FY18 for us to reach our goal of 1 billion monthly active devices," a Microsoft spokesman said in an emailed statement. "In the year ahead, we are excited about usage growth coming from commercial deployments and new devices - and increasing customer delight with Windows." Microsoft's fiscal year 2018 -- the "FY18" mentioned in the firm's statement -- ends June 1, 2018. Ed Bott of ZDNet first reported on Microsoft's admission.To read this article in full or to leave a comment, please click here

If Microsoft can’t install Windows 10 on your PC, it’ll give you a new one

As July 29 gets closer and the free Windows 10 upgrade offer reaches its final days, Microsoft is pulling out all the stops in order to convince users to upgrade. It’s even willing to give you a new laptop. As spotted by Neowin, Microsoft retail stores are offering to install Windows 10 on any compatible machine for free. If the store’s technicians don’t complete the upgrade by the end of that business day, they’ll give you a free 15-inch Dell Inspiron notebook.To read this article in full or to leave a comment, please click here

The H-1B positions of Clinton and Trump

With the political conventions set for the next two weeks, now is the time to offer a summary of where Donald Trump and Hillary Clinton stand on tech's top issue, immigration. Silicon Valley fears Trump, the presumptive Republican nominee for president. A letter released Thursday and signed by about 150 technologists, inventors and entrepreneurs, said Trump would be a disaster for innovation. Much of their criticism was directed at his proposed immigration policies. Clinton, the presumptive Democratic nominee for president, is far more aligned with Silicon Valley on immigration.To read this article in full or to leave a comment, please click here

AT&T likes ‘white-box’ networks and hopes you will, too

AT&T’s march toward standard “white-box” network gear will come to enterprises this week with the introduction of a standard x86 server that can take the place of four specialized network devices. AT&T is aggressively pursuing SDN and NFV (network functions virtualization), a pair of technologies that are expected to change the face of networking over the next several years. The carrier is on track to have nearly one-third of its own infrastructure virtualized this year. More important for enterprises, it’s offering customers a way to do the same thing at their own locations.To read this article in full or to leave a comment, please click here
