Plesk on DigitalOcean is now a one-click app

According to Alex Konrad, Forbes Editor of the Cloud 100 list, Cloud companies like DigitalOcean are revolutionizing how businesses reach their customers today. From digitizing painful old processes to allowing them more time to focus on what they really care about. This is what makes their products unique.

As a Web Professional (Developer, Agency owner, IT Admin) your goal is to provide valuable services to your customers. You want to be able to focus on the things you’re good at. And leave the nitty gritty of technical server management, cost streamlining, running instances, backups, and account management to a VPS. Because a virtual private server fits this purpose exactly. Tired of managing infrastructure and security, when what you want is to focus on coding and improving your product or service? Then Plesk Onyx is the ideal solution.

What is Digital Ocean?

We know DigitalOcean, founded in 2011, as a cloud infrastructure provider with a “developer first” mentality. They simplify web infrastructure for software developers and their mission is to smooth out the complexities of infrastructure. How? By offering one simple and robust platform for developers to easily launch and scale their applications. DigitalOcean is now the second largest and fastest-growing cloud computing platform of all public apps and websites, according to Netcraft.

6. Additional options such as Private networkingBackupsUser data, and Monitoring are not necessary for most Plesk users. Then click “Create”.

7. You can log in to your droplet using:

  • A root password, which you will receive by email. If you go with this option, skip the “Add your SSH keys” step and go to the next one.
    • Just type in your browser: https://<your-droplet-IP>:8443 . You will potentially see for 30 seconds some finishing procedure of the automatic deployment. Afterwards you will automatically land in the initial on-boarding of Plesk.
  • An SSH key. If you go with this option, click New SSH key to add a new SSH key or select a previously added key (if you have any).

Note: Using SSH keys is a more secure way of logging in. If you use a root password, we strongly recommend that you log in to the droplet command line and change the root password received by email. The command line will automatically prompt you to do so.

Deploying Plesk Onyx on Microsoft Windows Azure

Cloud computing provides businesses the ability to quickly scale computing resources without the costly and laborious task of building data centres, and without the costs of running servers with idle capacity due to variable workloads. To simplify dynamic provisioning in the Cloud for infrastructure providers (including service providers who offer dedicated servers, VPS or IaaS), Plesk now provides ready-to-go images for deploying on Microsoft Windows Azure.

What is Windows Azure?

Quite simply, anything you want it to be.

This cloud platform from Microsoft provides a wide range of different services, to help you build, deploy, and manage solutions for almost any purpose you can imagine. In other words, Windows Azure is a world of unlimited possibilities. Whether you’re a large enterprise spanning several continents that needs to run server workloads, or a small business that wants a website with a global reach, Windows Azure provides a platform for building applications that can leverage the cloud to meet the needs of your business.

In addition to traditional cloud offerings, Azure offers services that leverage proprietary Microsoft technologies. For example, RemoteApp allows for the deployment of Windows programs using a virtual machine running Windows, OS X, Android, or iOS through a remote desktop connection. Azure also offers cloud-hosted versions of common Microsoft enterprise solutions, such as Active Directory and SQL Server.

Questions about Windows Azure?

There are two great places you can go online to ask questions about Windows Azure and get answers from the community:

  • The Windows Azure forums on MSDN.
  • Get involved with the Azure Community on Stack Overflow here.

Here’s the good news: Plesk Onyx now runs on Microsoft’s cloud infrastructure to provide the scalability, security, and performance that customers depend on.

Better news yet, Plesk provides a variety of virtual machine images with the most popular configurations. So no actual installation is required. You’ll just need to create a virtual machine from the appropriate image. All available images for virtual machines can be found in the Microsoft Azure Marketplace.

 

Which virtual machine images are provided?

The new Plesk Onyx images are shipped in three editions and are available for both Windows and Linux.

The ‘Bring Your Own License’ (BYOL) instance of Plesk Onyx allows you to purchase your own license directly from the Plesk Online Store or from a Plesk reseller. For Plesk Onyx WebHost images, the cost of your license is included in the hourly charge for the instance. Plesk Onyx licenses are available for two platform types: for Dedicated Servers and for VPS.

License and OS version:
Plesk Onyx images at Microsoft Windows Azure

Now that you’re familiar with the Windows Azure platform and Plesk, you’re ready to take the next steps. And there’s no better way to experience the powerful capabilities of Windows Azure than trying out the platform for yourself.

 

Getting started with Plesk and Windows Azure

Microsoft is currently offering a free one-month trial of Windows Azure that provides you with $200 of Windows Azure credits you can use for whatever you want. You get full access to the platform with no strings attached. Just sign in with your Microsoft account and fill out the form.

Tutorials

These tutorials by Cynthia Nottingham, Technical Writer at Microsoft, shows you how easy it is to create a Windows virtual machine (VM) from a Plesk-published image by using the Azure portal.

 

Quick Start Guide: Create a virtual machine

Log into the Azure Portal and on your Dashboard, select New> Compute. Search for the Plesk virtual machine images and select the appropriate Plesk configuration.

Microsoft Windows Azure - Plesk Onyx images

When configuring a virtual machine, you will be asked to specify the following settings:

1. Basic settings: virtual machine name, disk type (SSD or HD), username and password, your Azure subscription and resource group.

Note: The root username cannot be used during the VM creation. You may grant the root user access to the VM later from the console.

For Linux VM, you can choose the following authentication types:

  • SSH public key. In this case, you should specify your SSH public key. You can find information about creating public and private SSH keys here.
  • Password. In this case, you should specify and confirm the password that will be used for connection to the virtual machine.

2. VM size. You can choose one of available standard sizes provided by Azure.

3. Storage and network settings, including virtual network, subnet, public IP address, network security group (firewall). It is OK to leave the default values for most options.

Note: By default, your machine will have a dynamic IP address, so that the IP address will be changed each time when the virtual machine is restarted. If you want to avoid this, click Public IP address and then select the Static option. The virtual machine will be created with a static IP address.

4. Deployment. When you’ve dialed in all the settings, you’ll be presented with a summary. Confirm these settings for your new VM and click OK. Finally, your offer details will be generated and you can now purchase your virtual machine by clicking the Purchase button. The deployment process will start, and you will see its progress on your Dashboard.

5. You’ve created a VM. Your new VM will deploy in a couple of minutes. Once your virtual machine is deployed, it will be automatically started and the setting page will be displayed. You also can view and manage your virtual machine settings by going to Virtual Machines and selecting your virtual machine name.

Of course, you will be able to see the Public IP address of the machine.

Access Plesk Onyx on your virtual machine

Connect to the virtual machine.

  • If you’ve created a Windows Virtual Machine, you can connect to it via Remote Desktop. Go to the Azure Portal Dashboard >Virtual Machines, choose your VM, and click Connect. This will create and download a Remote Desktop Protocol file (.rdp file) that acts like a shortcut to connect to your machine. Open this file and connect to your virtual machine using your login and password.

  • If you have a Linux VM, you can SSH into its public IP address that is displayed in the virtual machine’s settings. Depending on your selected authentication type, you may either use a login and password, or your SSH public key.

  • From a Mac or Linux workstation, you can SSH directly from the Terminal. For example:

     ssh -i ~/.ssh/azure_id_rsa [email protected]
  • If you are on a Windows workstation, then you will need to use PuTTY, MobaXTerm or Cygwin to SSH to Linux. For details, see How to Use SSH keys with Windows on Azure.

 

Get a one-time login for logging in to Plesk

  • On the virtual machine, run

     $ sudo plesk login

    to get a one-time login for logging in to Plesk. You will receive two links: based on the virtual machine name and based on the IP address. Use the link based on the IP address to log in to Plesk.

login via ssh to Plesk Onyx

Note: You cannot use the link based on the virtual machine name the first time you log in because Plesk has not passed the initial configuration and the full hostname has not been created yet. You should use the link corresponding to your public IP address.

 

Running the Installation/Configuration wizard

1. When you log into Plesk, you will see the View Selector page. On this page, you can choose the appearance of the panel as per your requirements.

Plesk Onyx configuration wizard
Image: Plesk Onyx

Once your purpose has been identified, a second drop-down menu will emerge asking you select your preferred layout. This can be changed later.

2. Then comes the Settings page. Here you need to fill in your hostname, IP configuration, and admin password.

  • New hostname: Fill in your primary domain (i.e. testdomain.com).
  • Default IP Address: Leave the IP as default.
  • New password: Change the default administrator password.

Plesk Onyx Settings
Image: Plesk Onyx

3. Next is the Administrator information page. Just fill in the information asked and proceed to the next page.

4. Then comes the License key install page. Your Microsoft Azure instance is billed on an hourly basis, starting when it boots up and ending with the instance termination.

  • If you have a Bring Your Own License (BYOL) Plesk Onyx image, your hourly charge for the Microsoft Azure instance will be lower but you need to purchase and install the Plesk product license yourself. You can order, retrieve and install a 14-day full-featured trial license from this page. Since you have already purchased a license key, proceeding with installing the license key.
  • If you have a non-BYOL Plesk Onyx image, for example, Plesk Onyx on Windows 2012 R2 (WebHost), the cost of the license will be included in the hourly charge for the instance.

5. On the Create your Webspace page you can specify the domain name of your first subscription, and system user account username and password that you will use to manage it. This will create a subscription for hosting multiple sites.

6. Woohoo! Plesk is now configured!

6 essentials on Docker containers

Docker containers

Docker is one of the most successful open source projects in recent history, it’s fundamentally shifting the way people think about building, shipping and running applications. If you’re in the tech industry then the chances you’re already aware of the project. We’re going to look at 6 key points about Docker.

According to Alex Ellis, Docker Captain, Containers are disruptive and are changing the way we build and partition our applications in the cloud. Gone are monolithic systems and in come microservices, auto-scaling and self-healing infrastructure. Forget heavy-weight SOAP interfaces – REST APIs are the new lingua franca.

Whether you are wondering how Docker fits into your stack or are already leading the way – here are 6 essential facts that you and your team need to know about containers.

1. Containers are not VMs

Containers and virtual machines have similar resource isolation and allocation benefits – but a different architectural approach allows containers to be more portable and efficient. The main difference between containers and VMs is in their architectural approach.

Difference between containers and VMs

Virtual machines

VMs include the application, the necessary binaries, libraries, and an entire guest operating system — all of which can amount to tens of GBs. VMs run on top of a physical machine using a Hypervisor.  The hypervisors themselves run on physical computers, referred to as the “host machine”. The host machine is what provides the VM with resources, including RAM and CPU. These resources are divided among VMs.  So if one VM is running a more resource heavy application, more resources would be allocated to that one than to the other VMs running on the same host machine.

The VM that is running on the host machine is also often called a “guest machine.”

This guest machine contains both the application and whatever it needs to run that application (e.g. system binaries, libraries). It also carries an entire virtualized hardware stack of its own, including virtualized network adapters, storage, and CPU — which means it in turn has its own full-fledged guest operating system. From the inside, the guest machine behaves as its own unit with its own dedicated resources. From the outside, we know that it’s a VM — sharing resources provided by the host machine.

Containers

For all intents and purposes, containers look like a VM. The *key* is that the underlying architecture is fundamentally different between the containers and virtual machines. The big difference between containers and VMs is that containers *share* the host system’s kernel with other containers. The image above shows that containers package up just the user space, and not the kernel or virtual hardware like a VM does.

Each container gets its own isolated user space to allow multiple containers to run on a single host machine. All the operating system level architecture is being shared across containers.

The only parts that are created from scratch are the bins and libs – this is what makes containers so lightweight and portable. Virtual machines are built in the opposite direction. They start with a full operating system and, depending on the application, developers may or may not be able to strip out unwanted components.

  • Basically containers provide same functionality which provides by VMs, with out any hypervisor overhead
  • Containers are more light weight than VMs, since it shares kernel with host without hardware emulation (hypervisor)
  • Docker is not a virtualization technology, it’s an application delivery technology.
  • A container is “just” a process – literally a container is not “a thing”.
  • Containers use kernel features such as kernel namespaces, and control groups (cgroups)
  • Kernel namespaces provide basic isolation and CGroups use for resource allocation

Namespaces

  • Kernel namespaces provide basic isolation
  • It guarantee that each container cannot see or affect other containers
  • For an example, with namespaces you can have multiple processes with same PID in different environments (containers)
  • There are six types of namespaces available
  1. pid (processes)
  2. net (network interfaces, routing…)
  3. ipc (System V IPC)
  4. mnt (mount points, filesystems)
  5. uts (hostname)
  6. user (UIDs)

CGroups

  • CGroups(Control Groups) allocate resources and apply limits to the resources a process can take (memory, CPU, disk I/O)
    between containers
  • It ensure that each container gets its fair share of memory, CPU, disk I/O(resources),
  • Also It guarantee that single container not over consuming the resources

2. A Container (Process) can start up in one-twentieth of a second

Containers can be created much faster than virtual machines because VMs must retrieve 10-20 GBs of an operating system from storage. The workload in the container uses the host server’s operating system kernel, avoiding that step. According to Miles Ward, Google Cloud Platform’s Global Head of Solutions, a container (process) can start up in ~1/20th of a second compared to a minute or so for a modern VM. When development teams adopt Docker –  they add a new layer of agility, and productivitiy to the software development lifecycle.

Having that speed right in place allows a development team to get project code activated, to test code in different ways, or to launch additional e-commerce capacity on its website –  all very quickly.
3. Containers have proven themselves on a massive scale
The world’s most innovative companies are adopting microservices architectures, where loosely coupled together services from applications. For example, you might have your Mongo database running in one container and your Redis server in another while your Node.js app is in another. With Docker, it’s become much more easier to link these containers together to create your application, making it easy-to-scale or update components independently in the future.

According to InformationWeek, another example is Google. Google Search is the world’s biggest implementer of containers, which the company uses for internal operations. In running Google Search operations, it uses containers by themselves, launching about 7,000 containers every second, which amounts to about 2 billion every week. The significance of containerization is that it is creating a standard definition and corresponding reference runtime that industry players will need to be able to move containers between different clouds (Google, AWS, Azure, DigitalOcean,…) which will allow applications and containers to become the portability layer going forward.
Docker helped create a group called the Open Container Initiative formed June 22nd 2015. The group exists to provide a standard format for container images and a specification for container runtimes. This helps avoid vendor lock-in and means your applications will be portable between many different cloud providers and hosts.
4. Containers are “lightweight”

As mentioned before, containers running on a single machine share the same operating system kernel – they start instantly and use less RAM. Docker for example has made it much easier for anyone — developers, sysadmins, and others — to take advantage of containers in order to quickly build and test portable applications. It allows anyone to package an application on their laptop, which in turn can run unmodified on any public cloud, private cloud, or even bare metal – the mantra is: “build once, run anywhere.”

Container architecture
5. Docker has become synonymous with containers
Docker is rapidly changing the rules of the cloud and upending the cloud technology landscape. Smoothing the way for microservices, open source collaboration, and DevOps. Docker is changing both the application development lifecycle and cloud engineering practices.

Stats:

  • 2B+ Docker Image Downloads
  • 2000+ contributors
  • 40K+ GitHub stars
  • 200K+ Dockerized apps
  • 240 Meetups in 70 countries
  • 95K Meetup members

Every day, lot’s of developers are happily testing or building new Docker-based apps with Plesk Onyx  – understanding where the Docker fire is spreading is the key to staying competitive in an ever-changing world.

Web Professionals understood that containers would be much more useful and portable if there was one way of creating them and moving them around, instead of having a proliferation of container formatting engines. Docker, at the moment, is that de facto standard.

They’re just like shipping containers, as Docker’s CEO Ben Golub likes to say. Every trucking firm, railroad, and marine shipyard knows how to pick up and move the standard shipping container. Docker containers are welcome the same way in a wide variety of computing environments.
6. Docker’s ambassadors: the Captains
Have you met the Docker Captains yet? There’s over 67 of them right now and they are spread all over the world. Captains are Docker ambassadors (not Docker employees) and their genuine *love* of all things Docker has a huge impact on the community.

That can be blogging, writing books, speaking, running workshops, creating tutorials and classes, offering support in forums, or organizing and contributing to local events.

Here, you find out on how you can follow all the Captains without having to navigate through over 67 web pages.

The Docker Community offers you the Docker basics, and lots of different ways to engage with other Docker enthusiasts who share a passion for virtual containers, microservices and distributed applications.

7. Alex Ellis – Docker Captain

I became a Docker Captain after being nominated by a Docker Inc. employee who had seen some of my training materials and activity in the community helping local developers in Peterborough to understand containers and how they fit into this shifting landscape of technology. The engergy and enthusiasm of Docker’s team was what lead me to start this journey on the Captains’programme.

It’s all about raising up new leaders in the community to advocate the benefits of containers for software engineering. We also write and speak about exciting new features in the Docker eco-system and  presence ourselves in conferences, meet-up groups and in the marketplace. Start my self-paced, Hands-On Docker tutorial here. If you have questions, or want to talk I’m on Twitter.

Thank you to Docker Captain Alex Ellis for co-authoring the introduction to this write-up and for providing feedback and technical insights on containers.

Be well, do good, and stay Plesky!

Cheers,
Jörg
