Alexander Grishin, ISPsystem’s Product Manager for VMmanager virtualization platform, shares his views on the topic.Hand and Physical Therapy Tips for Arthritis
Millions of people all over the world suffer from arthritis. In the present day, it is one of the most common medical conditions in the world. There is a common misconception about arthritis that it happens due to old age and that most people suffering from it are old. Where old age can affect your bones and joints health, people from all age groups can suffer from arthritis.
What Exactly Is Arthritis?
It is a medical condition that causes pain and inflammation in your joints. It can happen on joints on any part of the body. It can cause severe pain and affect your physical functioning. People who have arthritis in their hand joints have to tolerate excruciating pain. Our hands are something we have to use on a daily basis, and when you have arthritis in your hand joints then it can have severe consequences. You will not be able to perform any task if your hands aren’t at 100% health.
How Can Physical Therapy Be Used to Treat Arthritis?
There are many ways that arthritis can be treated. Doctors would always suggest medication and then ask you to focus on physical therapy as well. Physical therapy is as Continue reading

5G Is Not the Cure-All for Network Struggles
While building out 5G is important for mobile, the immediate focus should be on shoring up broadband networks that supply connectivity to people stuck at home.Exploring WebAssembly AI Services on Cloudflare Workers
This is a guest post by Videet Parekh, Abelardo Lopez-Lagunas, Sek Chai at Latent AI.
Edge networks present a significant opportunity for Artificial Intelligence (AI) performance and applicability. AI technologies already make it possible to run compelling applications like object and voice recognition, navigation, and recommendations.
AI at the edge presents a host of benefits. One is scalability—it is simply impractical to send all data to a centralized cloud. In fact, one study has predicted a global scope of 90 zettabytes generated by billions of IoT devices by 2025. Another is privacy—many users are reluctant to move their personal data to the cloud, whereas data processed at the edge are more ephemeral.
When AI services are distributed away from centralized data centers and closer to the service edge, it becomes possible to enhance the overall application speed without moving data unnecessarily. However, there are still challenges to make AI from the deep-cloud run efficiently on edge hardware. Here, we use the term deep-cloud to refer to highly centralized, massively-sized data centers. Deploying edge AI services can be hard because AI is both computational and memory bandwidth intensive. We need to tune the AI models so the computational latency and bandwidth Continue reading
Faucet Deep Dive on Software Gone Wild
This podcast introduction was written by Nick Buraglio, the host of today’s podcast.
In the original days of this podcast, there were heavy, deep discussions about this new protocol called “OpenFlow”. Like many of our most creative innovations in the IT field, OpenFlow came from an academic research project that aimed to change the way that we as operators managed, configured, and even thought about networking fundamentals.
For the most part, this project did what it intended, but once the marketing machine realized the flexibility of the technology and its potential to completely change the way we think about vendors, networks, provisioning, and management of networking, they were off to the races.
We all know what happened next.

Closing security gaps and eliminating blind spots in the data center: a software-based approach to securing east-west traffic
It’s no secret that traditional firewalls are ill–suited to securing east-west traffic. They’re static, inflexible, and require hair-pinning traffic around the data center. Traditional firewalls have no understanding of application context, resulting in rigid, static policies, and they don’t scale—so they’re unable to handle the massive workloads that make up modern data center traffic. As a result, many enterprises are forced to selectively secure workloads in the data center, creating gaps and blind spots in an organization’s security posture.
A software-based approach to securing east-west traffic changes the dynamic. Instead of hair-pinning traffic, VMware NSX Service-defined Firewall (SDFW) applies security policies to all workloads inside the data center, regardless of the underlying infrastructure. This provides deep context into every single workload.
Anyone interested in learning how the Service-defined Firewall can help them implement micro–segmentation and network segmentation, replace legacy physical hardware, or meet growing compliance needs and stop the lateral spread of threats, should check out the following sessions:

Meet compliance requirements cost-efficiently by implementing East-West security at scale
Compliance is more than a necessary evil. Sure, it’s complex, expensive, and largely driven by manual processes, but it’s also a business enabler. Without the ability to prove compliance, you wouldn’t be able to sell your products in certain markets or industries. But meeting compliance requirements can’t be cost-prohibitive: if the barriers are too high, it may not make business sense to target certain markets.
The goal, of course, is to meet and prove compliance requirements in the data center in a simple, cost-effective way. With the intent to provide safety and maintain the privacy of customers, new government and industry regulations are becoming more robust, and many require organizations to implement East-West security through micro-segmentation or network segmentation inside the data center. Of course, this is easier said than done. Bandwidth and latency issues caused by hair–pinning traffic between physical appliances inhibit network segmentation and micro-segmentation at scale.
VMware NSX applies a software-based approach to firewalling that delivers the simplicity and scalability necessary to secure East-West traffic. It does this with no blind spots or gaps in coverage— Continue reading
Intrinsic Security: Take security to the next level
The other guys will have you believe that more is better. You have a problem, just buy a solution and patch the hole. Security operations too siloed? Just cobble together some integrations and hope that everything works together.
VMware thinks differently. We believe that “integrated” is just another word for “complexity.” And clearly, complexity is the enemy of security.
Integrated security is bolted–on security. An example would be taking a hardware firewall and making it a blade in a data center switch. That’s what the other guys do. It makes it more convenient to deploy, but it doesn’t actually improve security.
Security always performs better—and is easier to operate—when it’s designed–in as opposed to bolted–on. At VMware, we call this intrinsic security. When we think about security, being able to build it in means you can leverage the intrinsic attributes of the infrastructure. We are not trying to take existing security solutions and integrate them. We are re-imagining how security could work.
Enterprises that want to learn how we’ve built security directly into Continue reading
Simplify your micro-segmentation implementations
Micro–segmentation is a critical component of Zero Trust. But, historically, micro-segmentation has been fraught with operational challenges and limited by platform capabilities.
Not anymore.
VMware NSX enables a new framework and firewall policy model that allows applications to define access down to the workload level. NSX does this by understanding application topologies and applying appropriate policy per workload. Creating zones in the data center where you can separate traffic by application simultaneously helps stop the spread of lateral threats, create separate development, test, and production environments, and meet certain compliance requirements.
VMworld attendees who want to learn more about how to set up micro-segmentation in their data centers should consider the following sessions:
Permit This, Deny That – Design Principles for NSX Distributed Firewall (ISNS2315D)
Micro-segmentation is something that is certainly easier said than done. Although micro-segmentation allows applications to define access down to the component level, the operation of such an environment can be daunting without structure and guidance. In this session, you’ll learn how to develop a Continue reading
Community Networks: Improving Connectivity for All in Haiti
The COVID-19 pandemic reminds us of the historic transition brought about by the Internet. Its place is real in our lives today and tomorrow. Celebrate, pray, play, study, work, express yourself … these verbs have been conjugated thousands of times everywhere thanks to the Internet. In Haiti, many suffer from the glaring inequality between Internet access in rural and urban areas. It is clear that tackling these problems comes down to building a safe path towards decentralization of Internet infrastructure here.
The mission of the Internet Society Haiti Chapter (ISOC Haiti) is to promote, on Haitian territory and for the benefit of all, the conditions and tools conducive to the development of an information and knowledge society – respectful of Haitian culture and values. Since 1804, our nation has raised its voice for freedom and equality so that every person may live free and in dignity, while banishing Black slavery on our land. Our motto, ‘’unity is strength,’’ reminds us that together we can achieve unimaginable things to change this nation. ISOC Haiti is aware of the challenges and believes it is time for a sustainable plan of action – and not for speech.
