Announcing the New Release of Docker Enterprise Edition

We are excited to share the new release of Docker Enterprise Edition. By supporting IBM Z and Windows Server 2016, this release puts us further in the lead with the first Containers-as-a-Service (CaaS) solution in the market for the modernization of all applications without disruption to you and your IT environment.

 

Docker Enterprise Edition 17.06

 

Docker Enterprise Edition (EE) 17.06 embraces Windows, Linux and Linux-based mainframe applications, bringing the key benefits of CaaS to the enterprise application portfolio. Most enterprises manage a diverse set of applications that includes both traditional applications and microservices, built on Linux and Windows, and intended for x86 servers, mainframes, and public clouds. Docker EE unites all of these applications into single platform, complete with customizable and flexible access control, support for a broad range of applications and infrastructure, and a highly automated software supply chain. These capabilities allow organizations to easily layer Docker EE onto existing processes and workflows, aligning to existing organizational structures while delivering improved resource utilization and reduced maintenance time.

This release includes UCP 2.2 and DTR 2.3 and establishes Docker EE as a key IT platform for both new application development as well as application modernization across both on-premises and Continue reading

IDG Contributor Network: 7 reasons mid-size tech companies should reconsider going all-in on public cloud

AWS primarily and Azure, of late, dominate today’s discussions around storage, backup and compute power. A quick glance at headlines from technology journalists, and a reader can glean a common coverage theme that ties these writers together — the ongoing discussion around the benefits of going all-in on the public cloud. However, in most cases technology journalists are writing about larger corporations, or big name installations, which may or may not reflect the actual trends taking place in the marketplace, especially at mid-size companies and organizations experiencing a growth spurt.As one who is regularly engaged with the CIOs at mid-size and smaller companies and organizations, I don’t see them going all-in on the cloud right now; rather some are pulling back from it and either opting a hybrid cloud solution, or are going all-in with on-prem backup solutions. In fact, according to a survey published by SMB analyst firm Techaisle LLS, the hybrid cloud is now being used by 32 percent of midmarket (100 to 999 employees) organizations, and that figure is expected to remain relatively flat at 31 percent into next year, in spite of what your read in the press about AWS or Azure penetration.To read Continue reading

IDG Contributor Network: What makes application delivery in China so hard?

At the end of 2016, China had over 700 million internet users, more than double the number of internet users in the U.S. And as the Chinese tech market continues to shift from hardware to software and services, Forrester Research analysts predict this will drive software growth of 10 percent over the next couple years.China is now a critical market for global technology companies and enterprises. It’s little wonder that tech giants like Apple, Facebook and others are clamoring to secure a hold there, even when it means addressing unique challenges and making certain compromises.To read this article in full or to leave a comment, please click here

Despite new silicon, 802.11ax isn’t coming to the enterprise for a while

The next great leap forward in Wi-Fi got a little closer to reality Tuesday with Broadcom’s announcement of a new family of chips designed to comply with the not-yet-finalized 802.11ax standard, but you might not need to game-plan for the arrival of 802.11ax products in the enterprise for quite awhile.However, thanks to several factors, including an unusual adoption cycle, the capabilities of existing Wi-Fi hardware and the standards process itself, 802.11ax is unlikely to take enterprise wireless customers by storm before late 2018, according to experts.+ ALSO ON NETWORK WORLD: Does MU-MIMO really expand Wi-Fi capacity? + 3 real-world examples of IoT rolled out in the enterprise + How Wi-Fi could get a boost from Li-FiTo read this article in full or to leave a comment, please click here

IPv6, Large UDP Packets and the DNS

It appears that rather than effecting a slight improvement from IPv4, the manner of fragmentation handling in IPv6 appears to be significantly worse than IPv4. Little wonder that there have been calls from time to time to completely dispense with packet fragmentation in IPv6, as the current situation with IPv6 appears to be worse than either no fragmentation or the IPv4-style of fragmentation.

Power outage hits the island of Taiwan. Here’s what we learned.

Power outage hits the island of Taiwan. Here’s what we learned.

At approximately 4:50pm local time (8:50am UTC) August 15, a major unexpected power outage hit the island of Taiwan with a significant amount of its power generation facilities going down.

Blackout!

Most of the island was hit with power outages, shortages and rolling blackouts, with street lights not functioning, nor power in many of Taipei’s shopping malls, and much other infrastructure.

Blackouts of this scale are very rare. Usually, during an outage of this scale, it would be expected that Internet traffic would greatly drop, as houses and businesses lose power and are unable to connect to the Internet. I’ve experienced this in the past, working at consumer ISPs. As households and businesses lose power, so do their modems or routers which connect them to the Internet.

However, during yesterday's outage, something different happened. I'd like to share some insights from yesterday's outage.

Even when the power is out, the Internet still operates

Most Telecom and Data Center facilities are built with redundancy in mind and have backup power generation. Our Data Center partner, Chief, was able to switch to backup power generation without any service interruption, allowing Continue reading

BrandPost: Going With Managed SD-WAN? Here’s How to Choose a Partner

SD-WAN is gaining tremendous traction among enterprises owing to the benefits it offers — cost savings from efficient use of low-cost Internet and wireless links, centralized control and management, network agility, speed to deployment of new sites, and optimized cloud connectivity—to list a few. And while a DIY model provides enterprise IT managers unprecedented flexibility and control over their WAN, a managed SD-WAN service may be better suited for businesses that prefer a turn-key service due to factors discussed in my previous blog.To read this article in full or to leave a comment, please click here
