Container Orchestration – Everything You Need to Know

With container orchestration, users can deploy, manage, scale, and network containers automatically. This is a significant time-saver for companies and hosts depending on the efficient deployment and management of Linux containers.

Container orchestration can be utilized wherever and whenever teams need to employ containers. One benefit of container orchestration is that it allows for the deployment of a single application throughout multiple environments, without it having to be reworked.

Furthermore, container microservices make orchestrating such key aspects as networking, storage, and security simpler.

Containers offer any apps based on microservices a fantastic deployment unit and self-contained environment for executions. This enables teams to run several independent elements of an app in microservices on one piece of hardware, while enjoying better control over the individual components and lifecycles.

Managing containers’ lifecycles with orchestration helps DevOps teams to integrate it with CI/CD workflows. That’s why containerized microservices are fundamental for cloud-native applications, along with APIs (Application Programming Interfaces).

Why teams work with container orchestration

Teams can take advantage of container orchestration for the automation and management of:

  • Allocating resources
  • Scheduling and configuring
  • Finding available containers
  • Provisioning & deployment
  • Routing traffic and balancing loads
  • Scaling/taking out containers according to variable workloads
  • Tracking health of containers
  • Maintaining security between interactions
  • Configuration of applications based on the respective containers chosen to run them

As you can see, container orchestration has the power to streamline processes and save considerable time.

The right tools for container orchestration

Container orchestration tools offer a framework with which to manage any containers as well as microservices design at scale. Various container orchestration tools are available for management of container lifecycles, such as Docker Swarm, Kubernetes, and Apache Mesos.

In a discussion of Apache Moss vs Docker Swarm vs Kubernetes, the latter may be more popular.

Kubernetes was originally created and built by Google engineers, as an open source project. Google donated Kubernetes to its Cloud Native Computing Foundation back in 2015. This tool enables teams to make application services across several containers, as well as scheduling containers throughout a cluster, scaling said containers, and managing their individual health conditions down the line.

This tool does away with a lot of manual tasks required to deploy and scale containerized applications. You also have the flexibility to cluster host groups, virtual or physical machines, and run Linux containers. Helpfully, Kubernetes presents users with a platform for efficient, simple cluster management.

Furthermore, this tool helps teams to implement and depend on container-based infrastructure within production spaces. These clusters may be placed across multiple clouds, whether private, public, or hybrid. That’s why Kubernetes is such a terrific platform to host cloud-native apps which demand fast scaling.

Kubernetes helps manage workload portability and balancing loads through movement of applications with no need to redesign them at all.

The key elements of Kubernetes

Kubernetes consists of:


The Kubelet service is based on nodes, and analyzes container manifests to ensure relevant containers start running.


A number of nodes, including one or more master nodes and multiple worker nodes.


This is the machine responsible for controlling Kubernetes nodes, and all task assignments come from here.


This is a group of multiple containers all deployed to an individual node. These containers share an IPC, IP address, and host name (along with additional resources).

How container orchestration functions

Any teams which leverage container orchestration tools (including Kubernetes) will describe an application’s configuration through JSON or YAML files. A configuration file informs the container management tool where container images are located. It also specifies the network establishment process, and where logs should be place.

In the implementation of a new container, the container management tool will schedule the deployment to a designated cluster in an automated process. It will also locate the right host, and take the specific requirements or limitations into account. After this, the orchestration tool handles managing the container lifecycle according to the specifications determined within the compose file.

Teams can utilize Kubernetes patterns for management of container-based applications or services, across configuration, lifecycle, and scaling. A Kubernetes developer depends on these repetitive patterns to build a complete system.

Container orchestration may be leveraged in a setting which requires utilization of containers, such as for on-site servers or private/public cloud processes.

Next Level Ops Podcast: Must Haves for Managed WordPress Hosting with Andrey Kugaevskiy

Next Level Ops Podcast: Must Haves for Managed WordPress Hosting with Andrey Kugaevskiy - Plesk

Hello Pleskians! This week we’re back with the fifth episode of the Official Plesk Podcast: Next Level Ops. In this installment, Superhost Joe speaks to Andrey Kugaevskiy, Plesk’s WordPress Paladin. Andrey tells us what to consider when setting up or looking for Managed WordPress Hosting.

In This Episode: Car Mechanics, One-click Hosters, Outdated Plugins, and More - Next Level Ops Podcast: Must Haves for Managed WordPress Hosting with Andrey Kugaevskiy - Plesk

How well do you know your hosting? Is your website, blog or e-commerce store secure and up to date? Do you get all the support you need? According to Andrey, choosing the right Managed WordPress Hosting is not a bed of roses. It’s, in fact, quite a tricky decision. 

For Andrey, hosters that specialize in WordPress take the pole position. Because every fast, modern, and secure Ferrari has a super-qualified team behind it. “A good Managed WordPress Hosting should handle the things you shouldn’t care about – like the technical infrastructure. So you should only be focused on growing your site or application”, says Andrey. 

Thank you master Andrey for your wise words. We’ll make sure our listeners follow your piece of advice when picking their Managed WordPress Hosting.

“A good Managed WordPress Hosting should handle the things you shouldn’t care about - like the technical infrastructure. So you should only be focused on growing your site or application.”

Andrey Kugaevskiy

Key Takeaways

  • Do your research beforehand: When choosing your hoster, make sure you spot the WordPress connoisseur. Having knowledgeable staff that can support you and your site, makes all the difference.
  • Know your resources and competence: Look at how many visitors you’ll have. There’s a big tech stack running on the hardware (Web, MySQL, PHP, Cache, security). And security is in a weird place right now between totally locked down and unusable, and more free-flowing and open. It’s a question of your knowledge, flexibility, and control.
  • Let your hoster take care of you: Managed WordPress Hosting should care about security issues and good performance. Outdated plugins are a common security problem. It’s important to keep your site up to date. And learn how to optimize your site for better results.
  • WordPress is here to stay: WordPress is growing extremely fast. So, it’s pretty clear that all hosts should have some kind of WordPress support. And most importantly, a bunch of experts. Hosts that don’t do anything for support, could face being left behind.

Alright Pleskians, it’s time to hit the play button if you want to hear the rest. You can listen to our previous episodes here and here. Or if you want to simplify the way you manage your website, you can also take a peek at our WordPress Toolkit. We’ll be back soon with the next installment!

Children’s Day Reflections, Brought To You By Our Favorite Pleskians

Children’s Day Reflections, Brought To You By Our Favorite Pleskians - Plesk

Hello Pleskians! As we’re all hunkered down doing remote work in the last months, we’ve celebrated all manner of things while staying indoors. On June 1, we commemorate the International Day for the Protection of Children. At Plesk, we honored the day by donating to our favorite charity. They have some incredible initiatives for children so do take a look and show them some support.

Meanwhile, we ventured out (virtually, of course) to find out how some of our favorite Pleskians celebrate being with their children.

Geo-caching with the Kids Has its Own Rewards

Our Chief Technical Officer, Jan Loeffler, recounts some of his favorite activities to do with his family. 

“My kids and I love climbing on rocks in nature, or something we call “Schnitzeljagd, which has nothing to do with Schnitzel as we are all vegetarians anyway,” says Jan. He compares the family sport to geo-caching as they split into two groups. “My wife goes for a hike in the forest near our house while leaving a trace with chalk or paper arrows and sometimes hiding some sweets as a treasure. My kids (a son and a daughter) and I follow the trace 10 minutes later and try to find her and the hidden treasures.”

On the values he deems important for his kids, he tells me, “One of the most important values we are trying to teach our children is self-confidence, since it’s required to explore new things,” says Jan. “But also tolerance, sustainability and discipline.” Jan mentions that he’s very curious about how their children will be when they grow up.

Good Old-fashioned Grit is the Way to Go

Irina Sfetea, Marketing Lead at Plesk, tells us about her five year old son who is a huge Lego fan, “Currently at the crossroad between Duplo and City. When he isn’t trying to sneak in on the daily team calls, my husband and I managed to keep him busy building planes, cars and switching heads between Lego figurines, as well as … pretending to cook jam in his play kitchen.” He also enjoys listening to stories and they’ve just finished reading the Chronicles of Narnia. “Now all lion toys are called Azlan.” 

Well, as C.S. Lewis said, sometimes growing old means that we’re old enough to start reading fairy tales again. 

And what values are important for Irina? “Patience, first of all,” says Irina, “It will get you a long way and will save you from a lot of frustration when times are rough.” She feels that kindness, compassion, and, ultimately, empathy are also important, “Because in most cases you reap what you sow, and putting yourself in the other person’s shoes will provide you with a chance of solving most challenges.” And finally, good old-fashioned grit, “The combination of resilience and self-trust, which ensures success in basically any domain, from personal to professional.”

There’s Always Time for Grand Adventures

For Julius, SEO Manager at Plesk, spending time with his children is all about adventure. “It can be about escaping to the mountains for hiking and enjoying the picturesque views of Pyrenees, visiting the nearest beach to have a decent swimming competition, or just playing computer games in multiplayer mode with your own team of 3 sons.”

As for values, it’s the ability to make decisions and take responsibility about them as one of the most important things to teach their children. “Rational acting with control over emotions is another aspect we consider to be significant,” says Julius.

Remembering and Honoring Children’s Day

Of course in the current situation, it’s been hard on everyone to continue their outdoor activities safely. For Irina and her family, who are all biking aficionados, being in Germany means that they are allowed to go outside, as long as they don’t meet other families. “We take advantage of all sunny weekends and go out for small hikes around our city.” For Julius and his family in Spain, things have also been difficult. “We are a bit limited in terms of outdoor activities, so backyard basketball battles proved to be a good substitute.”

We hope that things start changing soon for the better. And that we’re able to once more enjoy time outdoors. As they say, ‘tis the season. 

Happy Children’s Day, Pleskians!
