Serverless Computing: Ready for Prime Time The cloud ushered in a fundamental change in the way applications are deployed. Instead of worrying about how much dedicated hardware to order for your data center, you simply spin up as many servers as you need to do the job, then decommission them once the job is done. Yet, you still have to plan how many servers you will need at each stage of processing; you still have to remember to decommission them when done; and you pay for the entire virtual machine during the time you use it even though the server may be idle for most of that time. The next stage in the evolution of the cloud is serverless computing. After all, the servers you order in the cloud are only a means to an end - they provide the plumbing needed to run your code in response to various events. In the serverless computing paradigm, you supply the set of e... (more)

The Titanic and Your Network: 37 Seconds from Disaster? | @CloudExpo #Cloud #Cybersecurity

The Titanic and Your Network: 37 Seconds from Disaster? Put yourself in the shoes of Captain Edward Smith of the RMS Titanic, seconds after the iceberg was reported to him and seconds (there were 37 of them, reportedly) before he reacted. In this critical timeframe - this brief space of time when the inevitability of disaster became clear - was the great ship's fate decided? Like the maritime world before marine radar, there are times in IT security when the iceberg of an attack remains shrouded in fog and invisible. Yet there are also times when disaster is clearly right in front of us. It is these times - when we can see the data breach coming and need to steer the ship around it - that truly test our foresight. When Can You See It Coming? There are many clear indicators of impending attacks and scenarios in which attacks are likely. The question is whether we're a... (more)

Immutable Servers in a #Serverless World | @DevOpsSummit #AI #DevOps

Snowflakes are beautiful, unique creations. But, let's keep them in nature. They don't belong in our server infrastructure. Snowflake servers, where every configuration is just a little different, can introduce unnecessary security vulnerabilities and complications. While common in IT infrastructure, in the DevOps realm, they are gradually becoming ancient history. At the recent All Day DevOps conference, Erlend Oftedal (@webtonull), with Blank and head of the OWASP Norway chapter, discussed the benefits of immutable infrastructure practices within serverless architectures. Erland walked us through the positive effects on security as well as offered insight on potential problems. Erlend outlined the progress from physical servers to immutable servers, discussing the benefits of each step and the concerns that lead to the next phase, ending with immutable servers ... (more)

A New DNS for #IoT and #DevOps | @CloudExpo #AI #ML #RTC #DNS #M2M

Goodbye, Open Source: A New DNS for a New Internet BYOD. IoT. Cloud computing. DevOps. IT professionals today have more demands (and more acronyms) on their time than ever. Application development and delivery are changing rapidly and increasing in complexity, revealing the limitations of traditional DNS approaches in achieving modern network goals. The IT department has made use of open source platforms for decades to provide DNS and traffic management in their internal networks and for their public, internet-facing services. The majority of DNS servers, both on the internet and in enterprise intranets, are open source-based solutions such as BIND, djbdns, PowerDNS, gdnsd and NSD. It can feel like shoving a square peg into a round hole to try to adapt these solutions to perform the functions needed in today's environments. In addition, even with complex customizatio... (more)

You Are the Network | @CloudExpo #BigData #IoT #IIoT #M2M #API #DX #AI

First there was the Stone Age. Then we learned how to manipulate and smelt metals, which led to an Agrarian age. From there, machines helped bring about the Industrial age, then the Space Age. So where are we now? Shall We Call It the Network Age? Metcalfe's Law holds that the value of a connected network, telecommunications in the parlance of his day, is proportional to the square of the number of connected users. Or stated more simply, the utility of a connected ‘thing' increases as more and more ‘things' are connected. The telephone acts as an easy example. One phone by itself is a paperweight, but one million connected to the same network is immeasurably powerful. We live in a day of increasing connectivity. Think back to just a few years before the ubiquitousness of the Internet. How did we look up information? A phonebook for a phone number? An encyclopedia for ... (more)

[session] @Intel to Present #Kubernetes at @DevOpsSummit NY | #DevOps #AI

Advanced Network Scheduling and Isolation in Kubernetes Using a Containerized Telco Solution Given the popularity of the containers, further investment in the telco/cable industry is needed to transition existing VM-based solutions to containerized cloud native deployments. The networking architecture of the solution isolates the network traffic into different network planes (e.g., management, control, and media). This naturally makes support for multiple interfaces in container orchestration engines an indispensable requirement. In his session at @DevOpsSummit at 20th Cloud Expo, Kuralamudhan Ramakrishnan, a Senior Network Software Engineer at Intel, will discuss a solution that aims to provide advanced scheduling and discovery of network features in Kubernetes. Through a CNI plugin we support accelerations (sr-iov/vt-d/ebpf/xdp), multi-tenancy/network and network... (more)

Five Network Metrics | @CloudExpo @AppNeta #APM #SaaS #AI #DataCenter

Five Network Metrics for a Cloud World By Christine Cignoli As the network has moved from a physical entity to a more abstract one, IT has valiantly kept pace by researching and deploying new network devices and functionality. IT teams have had to shift workloads and mindsets to the cloud and to SaaS providers, while remaining responsible for end-user experience-which is ever more important. It's a tangled web in the networking world today, but all is not lost. We recommend these five metrics as the building blocks to measuring end-user experience and network performance in the cloud. They'll likely look pretty familiar: They're the same old metrics as were useful in the pre-cloud world, and can offer valuable insights now, too (though you'll need to be able to see into the cloud to get them - AppNeta can help with this). 1. Latency. This metric measures the time it ... (more)

Your #IoT Network Needs Saving | @CloudExpo @128Technology #SDN #SDS

Four Signs Your Network Needs Saving The network is at the core of every business, yet the majority of today's networks were not designed to handle the next generation of business requirements. More than two decades ago the world standardized on the Transmission Control Protocol (TCP) / Internet Protocol (IP) stack and little innovation has taken place in routing since. Modern networks are built upon the same fundamental protocols established before anyone could envision current demands. This has given rise to an entire industry surrounding routers aimed at delivering bolt-on functionality such as firewalls and load balancers. This approach has resulted in outages and data breaches for businesses as these jerry-rigged networks continue to grow too complex, too fragile and too expensive to deliver the security, control and agility needed for cloud, mobile and IoT ap...

ROI with #Monitoring | @DevOpsSummit #DevOps #APM #Docker #Monitoring

By Steve Kliff, Editor There are several ways monitoring can save your business money, depending on the kind of business you run. While it's almost impossible to give solid numbers, think of monitoring as an insurance policy for your company, or a health plan for your system. In the best case, it can diagnose issues before they turn into problems, or in the worst case, it can get your system back on its feet in case of a service outage. How a monitoring system can save my business money First of all you might want to consider your operating costs. Take a look at your IT department; how did they deal with the last outage you experienced? Was your business offline? Could your suppliers get you on the phone? Did your order go through? A monitoring system can warn you if your server memory is reaching overload, or if your bandwidth is about to become saturated, and ale... (more)

Putting Things to Work in the "Internet of Things"

Connected cars, factory equipment and household products communicating over the Internet is increasingly becoming a reality – one that might soon elicit headlines like “Is the Internet of Things a big bust?” That’s because it’s one thing to connect a device to the Internet and direct data back to the manufacturer or service provider. It’s another, to derive new information from those data streams. The ability to analyze data in the IoT is critical to designing better products, predicting maintenance issues, and even improving quality of life. Understanding the Internet of Things The Internet is no longer just a network of people using computers and smart devices to communicate with each other. In the not too distant future, everything from the factory floor to a city street will be connected to the Internet. Three out of four global business leaders are exploring the... (more)
