Flannel is more than a warm, cozy and oversized fall shirt.

Really? Yes, really.

We live in a highly designed world - from inception through the full lifespan of a system, design plays a critical role in the success of your product or service. Usability and user experience (UX) are driven by a comprehensive process that includes a high level design strategy (“What should be built?”), interaction design (“How will the system work?”) and visual design (“What will the system look like?”). Do you know what is at the root of those decisions? Infrastructure.

In this article we will elaborate on the benefits of container-based infrastructure and how Kubernetes and Flannel (not the shirt) work together to help you utilize and manage your applications.

What are containers and what are the benefits of using them?

A container is an instance of an image. A base image is essentially a blank computer that can be configured to run services using a set instructions such as those provided in a DockerFile. To ensure a high level of modularity images are generally configured such that they contain only what is needed to run a particular service (such as a web server or a preprocessor such as PHP).

Tools such as Docker Compose help glue together several single purpose image modules into a running set of containers that serve a greater purpose such as running a full web application stack. Configurations such as a docker-compose.yaml file contains a rule set for how related containers should start, communicate and share resources. This configuration may be used to deploy an application on any host running a container runtime, such as Docker.

Benefits of a container-based system:

Increased software reliability when moving between environments:

Since containers hold everything needed to run an application, differences in operating systems and other computing environments will not have an impact on how your container runs.

Improved server usability and performance:

Unlike virtual machines, which require the application AND an entire operating system to run, containers can share a single platform. Due to their comparatively small size, a server could host many more containers than virtual machines. Additionally, containers, unlike virtual machines, boot up instantly and can be closed just as quickly, allowing for improved resource availability on their host.

Expanded modularity capabilities:

Containerization allows for flexibility when packaging your complex application. Applications can be split into modules, allowing for easier management and reprogramming.

What programs are available to deploy and maintain containerized applications?

Kubernetes, an open-source container management platform developed by Google, is by far the most popular container management system available and it’s open-source. Multi-container infrastructure technology is the future, and Kubernetes offers the whole package.

Benefits of Kubernetes:

Efficient container management:

Kubernetes allows you to cluster multiple hosts. The Kubernetes scheduling component allows you to set rules for how your containers should run within the host cluster and then does everything within its power to ensure that the state of your running containers matches your rules. Kubernetes scheduling rules can be leveraged to greatly simplify advanced infrastructure operations such as advanced networking configurations, persistent storage for containers, vertical and horizontal scaling of hosts and services, healthchecks, centralized log output and self healing. Configurations are flexible to ensure that any application can be setup to run smoothly.

High level of compatibility:

Kubernetes supports multiple development languages, including Spring, Java, .NET, .NET Core, Go, Ruby, and more, meaning it will easily integrate with your existing technologies.

Exceptional hardware utilization:

Kubernetes is able to efficiently utilize existing hardware, potentially decreasing your overall hardware costs.

Error detection:

Kubernetes, through self-healing, automatically detects, analyzes, reports and attempts to repair container errors. Moreover, through a unique replication process, Kubernetes has self-correcting abilities  to keep your container functioning.

So how does Flannel fit into this?

Flannel is a useful design tool that can be implemented in conjunction with Kubernetes to connect containers across multiple hosts.

Kubernetes provides the foundation for running and managing containers running across a cluster of hosts but it does not provide a solution for network communication from container to container. This is where Flannel comes in. Flannel provides a networking abstraction that allows for seamless communication between containers, even if they are running on different hosts in the cluster, without the added complexities of port mapping or complex configuration.

Cyber Security is Quickly Becoming a Small Business Priority

There is news about cybercrime almost every day, concerning everything from large companies to the United States government. These news reports often give small business owners a false sense of security, thinking “this attack won’t happen to me, I’m too small!” However, as of 2016, 43% of small businesses are attacked. This statistic may be staggering, but hopefully, it is a wake-up call. Luckily, small businesses are not helpless. There are several steps you can take to protect your small business.  These include emphasizing privacy, planning ahead for the occurrence of a cyber attack, proper employee training, outsourcing security and integrating with the cloud.

Hackers have become smarter, more creative, and more dangerous.  That is why, now more than ever, businesses need developers on their side that can think one step ahead of hackers. Troy Web Consulting’s team of experts take great pride and care into every project they undertake, and look forward to new challenges and helping more people secure their information.

The Three ‘B’s’ of Cybersecurity for Small Businesses

This year, roughly half of American small businesses have been attacked by cyber criminals. While you may not be able to escape the threat of cybercrime, you can save yourself from becoming a victim. Small businesses are being attacked now more than ever, but if you follow these guidelines, your business may be able to avoid potential devastation by a cyber attack.

There are many different ways businesses can be attacked. One of them, and possibly the most notorious, is phishing. This is when an individual receives an email that appears to be from a co-worker, a supervisor, or anybody whom they may trust. In reality, this email is being sent by somebody who is waiting for the sensitive information they requested while in disguise. How can you prevent this?

  • Be aware. We have all heard about how we should create un-guessable passwords and never use the same one for more than one site, but how many people actually follow those  words of wisdom?
  • Be organized. This means creating secure passwords, and avoiding the use of possibly compromised equipment (i.e flash drives, rewritable CD’s, etc.). Lastly, small businesses need to
  • Be proactive. Businesses should regularly evaluate systems to identify vulnerabilities. Businesses should also make a habit of monitoring who enters the network. When an intruder is detected and an attack ensues, you and your business need to act swiftly in order to avoid destruction. After the attack is completed, it is important to recover quickly to return back to business as usual and to avoid another attack.

After learning and practicing these “Three B’s,” a business could always use an extra layer of armor for their information. That’s where custom software development comes in. At Troy Web Consulting, we place  great pride and care into every system we develop. We make sure that everything we create is current and safe, so your information is protected properly.
