You may have thought that you will soon have to embrace digital transformation and what our digital era brings to the table. The benefits of doing so are, after all, numerous. And no matter if you want to move your existing systems to the Cloud, or establish there the backbone of your newly founded business from the beginning, the AWS platform is undoubtedly one of your best choices. Our topic is, of course, Amazon VPC.

    Getting closer to the Python community

    Getting closer to the Python community

    My interest in Python began rather early in my career, as it was my first programming language, to learn. Since then, I’ve been constantly building knowledge on it. Ηere at Stackmasters, I have the opportunity to use it daily. The team and I, we’re always building some pretty awesome things, using Python! But it never hurts to learn a few extra tricks alongside the Python community.

    Mastering OpenStack as a Stackmasters intern

    Mastering OpenStack as a Stackmasters intern

    I was looking for an opportunity to gather practical knowledge on OpenStack and Ansible. As a final year student and a member of the CONSERT lab in University of West Attica, I had already touched my fingers on cloud technology. And since Stackmasters is heavily involved in cloud management and OpenStack in particular, I chose them to apply for my internship. A Stackmasters intern, then!

    Hiring a Managed Service Provider

    Infrastructure centralization

    Nowadays, many IT specialists swear by the cloud. Insisting – and rightfully so, if you care about my opinion – that moving their company’s infrastructure there, has had a huge – positive – impact on their business evolution. With a Managed Service Provider or sans one.

    Disaster Recovery on the Cloud

    Disaster recovery on the cloud

    Business continuity is without doubt one of the most essential aspects a company faces. But how about in the cloud? We’ll be the first to admit that it’s a relatively new concept and as a result there’s a lot of hype and fanfare.

    This comes par for the course with the buzz that exists around cloud computing in general. And with hype comes misinformation, misconceptions and the like. But what’s the truth behind all the pomp and circumstance?

    Private cloud: not just for the big boys

    Private cloud: not just for the big boys

    Private cloud. “This is not for me”. “It is too complicated and expensive”. “It’s only for large or corporate enterprises”. Right? Wrong.

    The fact is that from the various types of organizations out there, it’s the small and medium-sized firms stand to reap the most benefits by switching to cloud. So what’s the problem? Why don’t they? Basically. it comes down to knowledge. Very few (and we mean very) understand how it can help their businesses.

    A 3-step guide to moving to the cloud

    Move to the cloud

    Deciding to move your IT infrastructure to the cloud is no easy decision. Come to think of it, it’s a bit like moving house.

    The amount of planning, organization and baggage seems to stack up in front of you. And it can resemble a bit of a mini-mountain.

    Get your stack in tip top shape this summer

    Summer time and the living is easy. At least that’s the way things should be at this time of year, right?

    Wrong. It’s usually the season when there’s ample surfing (on the web that is), as well as new apps, software updates and IoT devices all stretching the limits of your Stack and IT system.

    Open source software in the modern data centre

    Open source software in the modern data centre

    There is an old quote that describes the progress of disruptive movements and technologies in this way: “First they ignore you, then they laugh at you, then they fight you, then you win”.

    Well, when it comes to Open Source in the data centre, we have been in the winning stage for quite a while now.

    Managed Services: infrastructure on tap

    Managed Services: infrastructure on tap

    In the beginning there was the lone systems administrator.

    He (for it was almost always a he) drank a lot of coffee, played a lot of PC games in the office, and knew all those arcane command line incantations to make your infrastructure work.

    Problem is, he was a single point of failure, being the only person who understood your system scripts and the ad-hoc and informal ways in which your servers where setup.

    Tip: Enable the new generation launch dialog in OpenStack

    Launch Dialog

    One of the most popular ways to manage an OpenStack cloud is through the Dashboard, codenamed Horizon. Although no one can argue the fact that it has improved a lot since the early days, there are still some things that need to be tweaked towards a better user experience.

    The launch instance dialog, for one, bugged me for a long time.

    Cloud 9: a sysadmin meets OpenStack

    For the past 7 years I have been working as a head system administrator with a tech startup incubator.

    Mine is the (often thankless) job of ensuring that the data center runs smoothly and securely and that business software, application servers and development environments are working and available to our users.

    Reach for the Cloud

    Reach for the cloud

    You’d think we’d all be accustomed to the Cloud by now. After all we’ve been hearing about Cloud technologies, Cloud this and Cloud that for over five years. But this is quite far from the truth when it comes to the enterprise Cloud.

    Construction on Abstraction

    Construction on abstraction

    From its humble beginnings in early 20th century to being our most essential infrastructure today, IT has come a long way. And it was mainly two techniques that helped it get where it is: ever increasing abstractions and a “divide and conquer” approach.

    Data Storage in clouds (#OSATH presentations)

    Last week we had another meeting with the local OpenStack User Group members #OSATH hosted at InnovAthens. It was exciting to see some of our old members progressing with their projects on OpenStack. Lots of new members and people interested in this community have also shown up, which is even more interesting and shows the traction OpenStack gets in Greece.

    OpenStack and Docker (Stackmasters’ #OSATH presentations)

    Docker in OpenStack

    If you follow the Greek OpenStack space you know that our involvement with the OpenStack community goes way back. As a matter of fact, in 2013, Stackmasters organized the very first OpenStack meetup in Greece, and we have been active promoting and evangelizing what we believe is the best open Cloud solution ever since, supporting #OSATH and organizing special events and training seminars.
