In the past couple of weeks, we have added some new operating systems
and applications into the OS templates line-up: CloudLinux, SUSE Linux
Enterprise Server and Dokku PaaS template for Ubuntu.
CloudLinux is a CentOS/RHEL-based operating system which is built and
suitable for shared hosting environment. It provides isolation between
users to avoid the “bad neighbour effect” where one user might be
consuming a lot of the server’s resources such as CPU, memory or I/O,
affecting the performance of other sites hosted on the same server.
This, in turn, will improve the stability of the overall server.
CloudLinux also has some other features, such as CageFS, which
provides virtualised per-user file system that uniquely encapsulates
each user, preventing users from seeing each other and viewing sensitive
information, thus improving security. Some other features of CloudLinux
include MySQL Governor, SecureLinks and PHP Selector.
To select CloudLinux OS template, choose “CloudLinux 6.4 (64-bit)
(excluding license)” from the list of OS templates when you make your
servelet order. CloudLinux is not an open source operating system, you
will need to purchase the license separately. More information about
CloudLinux operating system can be found on their website.
SUSE Linux Enterprise Server
SUSE Linux Enterprise server is a Linux-based operating system built
by SUSE, specialised to deliver mission-critical IT services efficiently
and cost effectively. Similar to CloudLinux, SUSE Linux Enterprise
Server is not free, and you would need to purchase the license
Take note that the vm_initialize script to initialize the data disk
doesn’t work on SUSE Linux, so you would need to initialize the
data-disk manually by following the instruction in our knowledge-base article here.
To select the SUSE Linux Enterprise Server template, please choose
“SUSE Linux ES 11 SP3 (64-bit”) from the list of OS templates when
making your servelet order. More information about SUSE Linux Enterprise
Server operating system can be found on their website.
Dokku is a mini-Heroku powered by Docker and written in less than 100
lines of bash. Once it’s set up on your servelet, you can push
Heroku-compatible applications to it via Git. This is suitable for
developers who like to use Heroku as their PaaS (Platform as a Service),
and this will provide your own, single-host version of Heroku running
on your servelet. We are using Ubuntu 12.04.3 LTS operating system for
the Dokku PaaS template.
To have the Dokku pre-installed on your Ubuntu servelet, please
select “Ubuntu 12.04.3 (64-bit) + Dokku” from the list of OS templates
when ordering your servelet. You would need to configure Dokku after the
servelet is provisioned by following the instructions on our knowledge-base article here.
More information about Dokku can be found on their website here and on the author’s blog here.
