Coming soon: Eco-friendly data centers | TECH(feed)

As the push for sustainability across all businesses intensifies, so too will the push for greener IT infrastructure. Data centers are notorious for giving off thermal energy and being somewhat energy inefficient. Researchers at Rice University are looking for solutions to turn this heat into something a little more useful. In this episode of TECH(feed), Juliet discusses the push for green IT and how data centers could become much more energy efficient.

Big Data and Kubernetes – Why Your Spark & Hadoop Workloads Should Run Containerized…(1/4)

Starting this week, we will do a series of four blogposts on the intersection of Spark with Kubernetes. The first blog post will delve into the reasons why both platforms should be integrated. The second will deep-dive into Spark/K8s integration. The third will discuss usecases for Serverless and Big Data Analytics. The last post will round off with insights on best practices. 

Introduction

Most Cloud Native Architectures are designed in response to Digital Business initiatives – where it is important to personalize and to track minute customer interactions. The main components of a Cloud Native Platform inevitably leverage a microservices based design. At the same time, Big Data architectures based on Apache Spark have been implemented at 1000s of enterprises and support multiple data ingest capabilities whether real-time, streaming, interactive SQL platform while performing any kind of data processing (batch, analytical, in memory & graph, based) at the same time providing search, messaging & governance capabilities.

The RDBMS has been a fixture of the monolithic application architecture. Cloud Native applications, however, need to work with data formats of the loosely structured kind as well as the regularly structured data. This implies the need to support data streams that are Continue reading

Exploring Batfish with Cumulus – part one

The topic of testing in continuous integration pipelines, is something we at Cumulus discuss almost daily, whether it’s internally or with customers. While our approach mainly centers around doing this type of testing in a virtual simulated environment, the moment I heard about a project called Batfish taking a different approach to testing, it had my attention. Better yet, once Batfish announced initial support for Cumulus earlier this year, there were no excuses left to not start digging in and understanding how it can fit into pipelines and replace or complement existing testing strategies.

The Batfish Approach To Testing

While there are various testing frameworks out there that help in building and organizing an approach to testing changes, the ugly truth is that the majority of this process occurs after a change has actually been pushed to a device. Techniques like linting provide some level of aid in the mostly empty pre-change testing area, but the control and data plane validation checks are forced to occur after a change has been pushed, when its generally “too late”. Even though there’s no argument that some testing is better than none, the pre-change test area is desperate for any type of visibility Continue reading

IDG Contributor Network: Intent-Based Networking (IBN): Bridging the gap on network complexity

Networking has gone through various transformations over the last decade. In essence, the network has become complex and hard to manage using traditional mechanisms. Now there is a significant need to design and integrate devices from multiple vendors and employ new technologies, such as virtualization and cloud services.Therefore, every network is a unique snowflake. You will never come across two identical networks. The products offered by the vendors act as the building blocks for engineers to design solutions that work for them. If we all had a simple and predictable network, this would not be a problem. But there are no global references to follow and designs vary from organization to organization. These lead to network variation even while offering similar services.To read this article in full, please click here

Kentik Turns AIOps Spotlight on Network Data, Workflows

San Francisco-based startup Avi Freedman, Kentik CEO. “They may say there’s a problem over in the network, but what is it? …We’re embracing [the network], but taking a more AI approach to surfacing insights and automation approach to what you do with that.” The AI-enabled capabilities include: Network operations insight into infrastructure and traffic across cloud, data center, WAN and campus environments, including traffic growth and capacity run-out dates. Edge network utilization and costs, including predicting cost overages and alerting on traffic spikes so teams can shift traffic to avoid network congestion. Network protection by setting smart baselines and thresholds to automatically recognize traffic anomalies, more easily investigate incidents such as DDoS attacks, and automatically prevent threats from causing performance and availability issues. The majority of Kentik’s early customers are service providers. AIOps can help them understand how their customers and subscribers use their services to more quickly Continue reading

The Week in Internet News: The Internet of Things and the Domain Name System

IoT vs. DNS: As the use of the Internet of Things grows, so do its threats on the Internet’s Domain Name System, Network World says. The Internet Corporation for Assigned Names and Numbers (ICANN) and IBM’s X-Force security researchers have both issued reports describing how the insecurity of IoT could lead to more botnets that attack the DNS.

A lot of zeros: The U.S. Federal Trade Commission announced an expected $5 billion fine against Facebook for privacy breaches, The Verge reports. Still, some critics suggested the fine was too small. Facebook’s revenue in 2018 was 11 times more than the fine, at $55.8 billion.

Not too big to investigate: Meanwhile, the U.S. Department of Justice has launched an antitrust investigation into Google, Amazon, and Facebook, Vox.com reports. The DOJ’s Antitrust Division is reviewing “whether and how market-leading online platforms have achieved market power and are engaging in practices that have reduced competition, stifled innovation, or otherwise harmed consumers.” 

Not just the DOJ: And the Federal Trade Commission is also getting into the antitrust investigations act. Facebook has announced that its friends at the FTC, fresh off their $5 billion fine of the social media Continue reading

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.

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.
