Don’t Miss Docker’s Hands-on Workshop at Arm TechCon 2019

Momentum is building for edge computing

With the rise of the Internet of Things (IoT) combined with global rollout of 5G (Fifth-generation wireless network technology), a perfect storm is brewing that will see higher speeds, extreme lower latency, and greater network capacity that will deliver on the hype of IoT connectivity.

And industry experts are bullish on the future. For example, Arpit Joshipura, The Linux Foundation’s general manager of networking, predicts edge computing will overtake cloud computing by 2025. According to Santhosh Rao, senior research director at Gartner, around 10% of enterprise-generated data is created and processed outside a traditional centralized data center or cloud today. He predicts this will reach 75% by 2025.

Back in April 2019, Docker and Arm announced a strategic partnership enabling cloud developers to build applications for cloud, edge, and IoT environments seamlessly on the Arm® architecture. We carried the momentum with Arm from that announcement into DockerCon 2019 in our joint Techtalk, where we showcased cloud native development on Arm and how multi-architecture containers with Docker can be used to accelerate Arm development.

DARPA looks for new NICs to speed up networks

The government agency that gave us the Internet 50 years ago is now looking to drastically increase network speed to address bottlenecks and chokepoints for compute-intensive applications.The Defense Advanced Research Projects Agency (DARPA), an arm of the Pentagon, has unveiled a computing initiative, one of many, that will attempt to overhaul the network stack and interfaces that cannot keep up with high-end processors and are often the choke point for data-driven applications.[Get regularly scheduled insights by signing up for Network World newsletters. ] The DARPA initiative, Fast Network Interface Cards, or FastNICs, aims to boost network performance by a factor of 100 through a clean-slate transformation of the network stack from the application to the system software layers running on top of steadily faster hardware. DARPA is soliciting proposals from networking vendors. .To read this article in full, please click here

Redis Cloud Gets Easier with Fully Managed Hosting on Azure

ScaleGrid, a rapidly growing leader in the Database-as-a-Service (DBaaS) space, has just launched their new fully managed Redis on Azure service. This Redis management solution allows startups up to enterprise-level organizations automate their Redis operations on Microsoft Azure dedicated cloud servers, alongside their other open source database deployments, including MongoDB, MySQL and PostgreSQL.

Redis, the #1 key-value store and top 10 database in the world, has grown by over 300% in popularity over that past 5 years, per the DB-Engines knowledge base. The demand for Redis is skyrocketing across dozens of use cases, particularly for cache, queues, geospatial data, and high speed transactions. This simple database management system makes it very easy to store and retrieve pairs of keys and values, and is commonly paired with other database types to increase the speed and performance of an application. According to the 2019 Open Source Database Report, a majority of Redis deployments are used in conjunction with MySQL, and over half of Redis deployments are used with either PostgreSQL, MongoDB, and Elasticsearch.

ScaleGrid’s Redis hosting service allows these organizations to automate all of their time-consuming management tasks, such as backups, upgrades, scaling, replication, sharding, monitoring, alerts, log rotations, and Continue reading

Is hybrid cloud certification right for you?

After years of shifting applications to the public cloud, enterprises realize it’s not the right fit for every app and are pulling some of them back to private clouds, forcing the businesses to adopt a hybrid strategy. But it’s not an easy process and one that may require formal training and certifications for the IT pros tasked with this important transition.“A huge desire to move to the cloud, and pressure from lines of business to move to the cloud, have created an experience gap that has led to serious missteps and forced IT teams to repatriate workloads they had put in the cloud back into the data center,” says Scott Sinclair, senior analyst at IT research firm ESG. “IT’s level of competence, experience, and education in how to integrate with the cloud is woefully inadequate.”To read this article in full, please click here

DC 15. Segment-routing/MPLS on the data centre white box switch and VNF/PNF networking (Nokia, Cisco and Mellanox/Cumulus).

Hello my friend,

the article today would be very special because of three following points. First of all, we’ll talk about the segment routing, which is the leading technology today for building service providers and emerging for DC. Second, you will learn how to connect VNFs with the real network devices. Third, we will fork Cumulus Linux with modified FRR. Thrilled? Let’s go!

Network Automation Beyond Configuration Templating

Remember Nicky Davey describing how he got large DMVPN deployment back on track with configuration templating? In his own words…:

Configuration templating is still as big win a win for us as it was a year ago. We have since expanded the automation solution, and reading the old blog post makes me realise how far we have come. I began working with this particular customer in May 2017, so 2 years now. At that time the new WAN project was on the horizon and the approach to network configuration was entirely manual.

Here’s how far he got in the meantime:

A New Twist On PCI-Express Switching For The Datacenter

While there are plenty of distributed applications that are going to chew through the hundreds of gigabits per second of bandwidth per port that modern Ethernet or InfiniBand ASICs deliver inside of switches, there are still others that might benefit from having a more streamlined stack that is also more malleable and composable. …

3 Layers to Defend Your Kubernetes Workloads

Researchers at Netflix and Google recently reported a vulnerability in the HTTP/2 protocol that enables adversaries to execute a DOS attack by legitimate use of the protocol. These types of attacks are very difficult to detect and mitigate because the traffic is valid HTTP/2 traffic. While HTTP/2 is a relatively new protocol it should be noted that even after several years of hardening we still see vulnerabilities for the TCP protocol like the recently reported SACK vulnerability.

Vulnerability Scanning and Patching

So how do we ensure that Kubernetes workloads are protected from these types of vulnerabilities?

Security researchers work to identify new vulnerabilities and then help developers develop security patches. You can apply those patches to keep your software secure from the lastest known vulnerabilities.

The simple answer then is to scan workload images and patch your software and update your software to use the latest patches. However, that approach essentially means you have to wait for the next attack and then will need to repeat the cycle. While this works, it is not sufficient and quite disruptive to implement as we play into the hands of the adversaries where they are working on the next vulnerability while Continue reading

Intel announces Optane for workstations, higher capacity NAND

At its Memory and Storage Day 2019 in Seoul last week, Intel made several announcements concerning its Optane persistent storage as well as NAND flash capacity.Optane is a new form of non-volatile memory from Intel that has the storage capacity of a solid state drive (SSD) but speed almost equal to DRAM. It sits between memory and storage to act as a large, fast cache. While some come in a PCI Express card design, the predominant design is DRAM memory sticks that plug into the motherboard. And they cost a fortune. A 512GB Optane stick will run you $8,000.See how AI can boost data-center availability and efficiency Intel announced a new generation of Optane memory codenamed "Alder Stream," which it said has a 50x lower failure rate than 3D NAND and also triples the transfers per second compared to the current generation of Optane on the market today.To read this article in full, please click here

Single Sign-On for Kubernetes: Dashboard Experience

Over my last two posts (part 1 and part 2), I have investigated user authentication in Kubernetes and how to create a single sign-on experience within the Kubernetes ecosystem. So far I have explained how Open ID Connect (OIDC) works, how to get started with OIDC and how to perform a login from the command line.

The final piece of this puzzle is the Kubernetes dashboard, often used by our engineers alongside kubectl. To complete our move to SSO, we wanted to ensure that, when using the Dashboard, our engineers logged in to the same account they used for kubectl.

Since Kubernetes version 1.7.0, the dashboard has had a login page. It allows users to upload a kubeconfig file or enter a bearer token. If you have already logged into the command line, this allows you to copy the OIDC id-token from your kubeconfig file into the bearer token field and login. There are, however, a couple of problems with this:

The login page has a skip button — If you aren’t using any authorization (RBAC) then this would permit anyone to access the dashboard with effective admin rights.
Copy and pasting a token from a Continue reading
