5 reasons to use Kubernetes

Kubernetes is the de facto open source container orchestration tool for enterprises. It provides application deployment, scaling, container management, and other capabilities, and it enables enterprises to optimize hardware resource utilization and increase production uptime through fault-tolerant functionality at speed. The project was initially developed by Google, which donated the project to the Cloud-Native Computing Foundation. In 2018, it became the first CNCF project to graduate.

This is all well and good, but it doesn’t explain why development and operations should invest their valuable time and effort in Kubernetes. The reason Kubernetes is so useful is that it helps dev and ops quickly solve the problems they struggle with every day.

Following are five ways Kubernetes’ capabilities help dev and ops professionals address their most common problems.

1. Vendor-agnostic

Many public cloud providers not only serve managed Kubernetes services but also lots of cloud products built on top of those services for on-premises application container orchestration. Being vendor-agnostic enables operators to design, build, and manage multi-cloud and hybrid cloud platforms easily and safely without risk of vendor lock-in. Kubernetes also eliminates the ops team’s worries about a complex multi/hybrid cloud strategy.

2. Service discovery

To develop microservices applications, Java developers must Continue reading

NVMe over Fabrics enterprise storage spec enters final review process

NVM Express Inc., the developer of the NVMe spec for enterprise SSDs, announced that its NVMe-oF architecture has entered a final 45-day review, an important step toward release of a formal specification for enterprise SSD makers.NVMe-oF stands for NVMe over Fabrics, a mechanism to transfer data between a host computer and a target SSD or system over a network, such as Ethernet, Fibre Channel (FC), or InfiniBand. NVM Express first released the 1.0 spec of NVMe-oF in 2016, so this is long overdue.To read this article in full, please click here

IT Burnout – The Task List

Sadly, this picture above is me. I used to think I had one of the best memories in the world. It turns out my memory is well-suited for bar trivia and routing protocol esoterics. My memory doesn’t appear so adept at remembering other little things that are of more important, such as remembering to buy a gift for a birthday or following up on an email that I sent last week.

Human brains are great at processing information. But some of the ones that are best at processing it are horrible at recalling it. I think of it not unlike a three-tiered storage array. The fast access tasks are in the fastest storage tier where they are needed. The longer term but less important info goes into the near-line tier where it can be recalled when needed. And in my case, the bandwidth to that tier is slow and unreliable.

Exciting Things!

One of my solutions to this problem is getting better with task management. As bad as my memory is, it’s also not well suited to writing things down to remember them. The irony is almost too delicious to ignore. I need to write things down so I don’t Continue reading

Not So Private Thoughts at IETF 105

At IETF 105, held in Montreal at the end of July, the Technical Plenary part of the meeting had two speakers on the topic of privacy in today's Internet, Associate Professor Arvind Narayanan of Princeton University and Professor Stephen Bellovin of Colombia University. They were both quite disturbing talks in their distinct ways, and I'd like to share my impressions of these two presentations and then consider what privacy means for me in today's Internet.

Verizon launches interconnect service through Equinix

Just days after AT&T hooked up with IBM and Microsoft for cloud service connectivity, Verizon announced a software-defined interconnect (SDI) service to help the carrier's customers connect Equinix colocation data centers.These two companies have a history. In 2017, Equinix acquired 29 Verizon data centers in the U.S and Latin America for $3.6 billion. So like AT&T, Verizon left data centers to the experts and focused on building connections to them. [ Read also: How to plan a software-defined data center network ] As more enterprises move workloads into colocation facilities run by providers like Equinix, fast, secure connections between the enterprise and the colocation become a must. Verizon's SDI service is designed to provide fast, reliable connectivity between customer and the colocation data center.To read this article in full, please click here

Software Engineers and Network Automation

I was saying “you’ll get the best network automation (or SDN) results if you pair network engineers with software engineers” for ages, but there’s always someone else saying it more eloquently, in this case Jeremy Schulman in his recent blog post.

Jeremy will talk about ChatOps in Autumn 2019 Building Network Automation Solutions online course, but of course you’re more than welcome to ask him other questions as well.

Report: Smart-city IoT isn’t smart enough yet

Security arrangements for smart-city IoT technology around the world are in an alarming state of disrepair, according to a report from Forrester Research that argues serious changes are needed in order to avoid widespread compromises.Much of what’s wrong has to do with a lack of understanding on the part of the people in charge of those systems and a failure to follow well-known security best practices, like centralized management, network visibility and limiting attack-surfaces. More on IoT: What is the IoT? How the internet of things works What is edge computing and how it’s changing the network Most powerful Internet of Things companies 10 Hot IoT startups to watch The 6 ways to make money in IoT What is digital twin technology? [and why it matters] Blockchain, service-centric networking key to IoT success Getting grounded in IoT networking and security Building IoT-ready networks must become a priority What is the Industrial IoT? [And why the stakes are so high] Those all pose stiff challenges, according to “Making Smart Cities Safe And Secure,” the Forrester report by Merritt Maxim and Salvatore Schiano. The attack surface for a smart city is, by default, enormous, given the volume of Internet-connected hardware involved. Continue reading

IoT’s role in expanding drone use

As faithful readers of TechWatch (love you, Mom) may know, the rollout of many companies’ ambitious drone delivery services has not gone as quickly as promised. Despite recent signs of progress in Australia and the United States—not to mention clever ideas for burger deliveries to cars stuck in traffic—drone delivery remains a long way from becoming a viable option in the vast majority of use cases. And the problem affects many areas of drone usage, not just the heavily hyped drone delivery applications.To read this article in full, please click here

Storage management a weak area for most enterprises

Stop me if you’ve heard this before: Companies are racing to a new technological paradigm but are using yesterday’s tech to do it.I know. Shocking.A survey of more than 300 storage professionals by storage vendor NGD Systems found only 11% of the companies they talked to would give themselves an “A” grade for their compute and storage capabilities.Why? The chief reason given is that while enterprises are rapidly deploying technologies for edge networks, real-time analytics, machine learning, and internet of things (IoT) projects, they are still using legacy storage solutions that are not designed for such data-intensive workloads. More than half — 54% — said their processing of edge applications is a bottleneck, and they want faster and more intelligent storage solutions.To read this article in full, please click here

Reports: As the IoT grows, so do its threats to DNS

The internet of things is shaping up to be a more significant threat to the Domain Name System through larger IoT botnets, unintentional adverse effects of IoT-software updates and the continuing development of bot-herding software.The Internet Corporation for Assigned Names and Numbers (ICANN) and IBM’s X-Force security researchers have recently issued reports outlining the interplay between DNS and IoT that includes warnings about the pressure IoT botnets will put on the availability of DNS systems.More about DNS: DNS in the cloud: Why and why not DNS over HTTPS seeks to make internet use more private How to protect your infrastructure from DNS cache poisoning ICANN housecleaning revokes old DNS security key ICANN’s Security and Stability Advisory Committee (SSAC) wrote in a report that “a significant number of IoT devices will likely be IP enabled and will use the DNS to locate the remote services they require to perform their functions. As a result, the DNS will continue to play the same crucial role for the IoT that it has for traditional applications that enable human users to interact with services and content,” ICANN stated. “The  role of  the  DNS  might  become  even  more  crucial  from  a  security  and  stability Continue reading
