Monitoring of Docker environments is challenging. Why? Because each container typically runs a single process, has its own environment, utilizes virtual networks, or has various methods of managing storage. Traditional monitoring solutions take metrics from each server and applications they run. These servers and applications running on them are typically very static, with very long uptimes. Docker deployments are different: a set of containers may run many applications, all sharing the resources of one or more underlying hosts. It's not uncommon for Docker servers to run thousands of short-term containers (e.g., for batch jobs) while a set of permanent services runs in parallel. Traditional monitoring tools not used to such dynamic environments are not suited for such deployments. On the other hand, some modern monitoring solutions (e.g. SPM from Sematext) were built with such dynamic systems in mind and even have out of the box reporting for docker monitoring. Moreover, container resource sharing calls for stricter enforcement of resource usage limits, an additional issue you must watch carefully. To make appropriate adjustments for resource quotas you need good visibility into any limits containers have reached or errors they have caused. We recommend using alerts according to defined limits; this way you can adjust limits or resource usage even before errors start happening.
The visual model to declarative metadata representation to immutable deployment vision is in essence what SD is all about. The secret to making this approach practical, and thus the key to understanding why SD approaches have become so prevalent, is the word immutable. Once we get an SD approach right, we no longer have to touch the deployed technology whatsoever. Instead, to make a change, update the model and redeploy.
Enterprise architects are increasingly adopting multi-cloud strategies as they seek to utilize existing data center assets, leverage the advantages of cloud computing and avoid cloud vendor lock-in. This requires a globally aware traffic management strategy that can monitor infrastructure health across data centers and end-user experience globally, while responding to control changes and system specification at the speed of today’s DevOps teams. In his session at 20th Cloud Expo, Josh Gray, Chief Architect at Cedexis, will cover strategies for orchestrating global traffic achieving the highest-quality end-user experience while spanning multiple clouds and data centers and reacting at the velocity of modern development teams.
We talked a bit about the Software Development Life Cycle (SDLC) in a recent post, but today, we're going to dig a little deeper into one specific and crucial element in the testing phase, particularly for Agile development: regression testing. Regression testing refers to the process of testing a changed or updated computer program to make sure the older software features - which were previously developed and tested - still performs exactly as they did before. One way to think about software regression is to think about somebody who implements a new air conditioning system in their home only to find that while their new air conditioning system works as expected, the lights no longer work.
While I am all for traditions like Thanksgiving turkey and Sunday afternoon football, holding onto traditions in your professional life can be career limiting. The awesome thing about careers in technology is that you constantly have to be on your front foot. Because when you’re not, someone, somewhere, will be and when you meet them, they’ll win. One tradition that has a limited lifespan at this moment is waterfall-native development and the security practices that go along with them. While the beginning of the end might have first been witnessed when Gene Kim and Josh Corman presented Security is Dead at RSA in 2012, we have more quantifiable evidence from the 2017 DevSecOps Community Survey. When asked about the maturity of DevOps practices in their organizations, 40% stated that maturity was improving, while 25% said that it was very mature across the organization or in specific pockets.

Automation, a key pillar of the DevOps movement, frees IT operations to focus on higher-levl work and collaborate with cross-functional teams. But what if your automation is so good that developers don’t need you anymore? Mike Gualtieri of Forrester Research coined the term NoOps in his controversial blog post “I don’t want DevOps. I want NoOps.” In the post, Gualtieri says, “NoOps means that application developers will never have to speak with an operations professional again.”

Developers want to create better apps faster. Static clouds are giving way to scalable systems, with dynamic resource allocation and application monitoring. You won't hear that chant from users on any picket line, but helping developers to create better apps faster is the mission of Lee Atchison, principal cloud architect and advocate at New Relic Inc., based in San Francisco. His singular job is to understand and drive the industry in the areas of cloud architecture, microservices, scalability and availability. In a keynote presentation, he spoke to a standing-room-only crowd at New York's Cloud Expo about how highly available, highly scalable systems can help developers attain the goal of better apps faster.
SYS-CON Events announced today that Twistlock, the leading provider of cloud container security solutions, will exhibit at SYS-CON's 20th International Cloud Expo®, which will take place on June 6-8, 2017, at the Javits Center in New York City, NY. Twistlock is the industry's first enterprise security suite for container security. Twistlock's technology addresses risks on the host and within the application of the container, enabling enterprises to consistently enforce security policies, monitor and audit activity and identify and isolate threats in a container or cluster of containers.
Wouldn’t it be great if there were tiny robots that kept track of what you were thinking, then helped you implement your plans automatically? Well, if you’re an admin responsible for monitoring infrastructure, they exist. They’re called chatbots, and they are the key to leveraging ChatOps in order to optimize your monitoring and incident management workflow. This post explains what chatbots and ChatOps do and why they're so valuable for organizations that are adopting DevOps practices.
In his keynote at 19th Cloud Expo, Sheng Liang, co-founder and CEO of Rancher Labs, discussed the technological advances and new business opportunities created by the rapid adoption of containers. With the success of Amazon Web Services (AWS) and various open source technologies used to build private clouds, cloud computing has become an essential component of IT strategy. However, users continue to face challenges in implementing clouds, as older technologies evolve and newer ones like Docker containers gain prominence. He explored these challenges and how to address them, while considering how containers will influence the direction of cloud computing.
Businesses are being driven up against the wall by continual industry disruption. Many are fighting back by adopting Lean as a means to support business transformation. The aim is simple: create more value for customers with fewer resources. Lean thinking views the whole, not its parts. Then it identifies and eliminates waste across value streams. Here’s how you can implement Lean thinking to improve your enterprise release management,
We are experiencing a ‘crisis of engagement,’ according to a survey by management consultancy Gallup, with a staggering 87 percent of employees worldwide disengaged with their jobs. While there are many factors that can influence an employee’s contentment – from support to compensation to job security – a common grievance in software development is disempowerment, where talented individuals are feeling hampered by their working environment.
Cloud is a lot more pervasive than one may have imagined and in this article, we will focus on the various ways in which cloud technology is making home security systems robust and impenetrable. The term ‘Internet of Things’ gets thrown around quite a lot when we talk about cloud technology in domains outside of computer systems. But cloud technology in areas like home security is not merely about IoT.

In the run up to our latest release of capabilities for developers, I sat down with David Yang, a senior engineer here at PagerDuty who’s seen our internal architecture evolve from a single monolithic codebase to dozens of microservices. He’s the technical lead for our Incident Management – People team, which owns the services that deliver alert notifications to all 8,000+ PagerDuty customers. We sat down and talked about life after switching to teams owning the operations of their services. Here are some observations about the benefits and drawbacks we’ve seen:
Common items are becoming “smarter.” IoT is making an impact on businesses across the board, including commercial buildings, manufacturing, retail and events. You‘ve probably heard of the Internet of Things by now, and if you haven't, you might be surprised to discover it's likely already made an impact on your life. The Internet of Things, or IoT for short, refers to connecting everyday objects to the internet and allowing them to exchange data on their performance and the environment. By gaining the ability to communicate, common items you interact with every day are becoming "smarter." IoT is making an impact on businesses across the board, including commercial buildings, manufacturing, retail and events.
Big Data is literally everywhere, and consumers interact with it daily. However, it’s the marketers that recognize the value of such data and use it to perfect the customer experience. Consumers, on the other hand, are often oblivious to their contribution to the mass data that marketers and businesses use to design their products and services. They don’t realize that their phones actually ping location-based data to nearby retailers. Browsing history, social media shares, online transactions, subscriptions, and other online interactions also provide information that marketers use to know more about their consumers.
