GGD#54 ‘ Virtual Machine vs. Container’ with Kate Mallichan

Our September Girl Geek Dinner is hosted by HP labs

Wednesday September 21st 

Kate Mallichan graduated in 2007 from the University of Bristol with an MEng in Computer Science. She worked for 5 years in industrial software engineering across a broad spectrum of fields that included mobile apps, aerospace systems and roadside sensor equipment. She has experience in an equally wide range of software development languages and tools. A thirst for more creative freedom led her to join HP Labs  in 2012 as a Research Engineer. Since that time her focus has been on rapid prototyping in the areas of cloud computing, cyber-security and more recently container technologies.





Virtual Machine vs. Container

Virtual machines are essentially a software emulation of a complete computer system, including hardware and OS. They have existed in some form since the 1960s, though they were not widely adopted until technologies matured in the 2000s and they became a primary enabler of the cloud computing paradigm.

Containers can be thought of as a light-weight form of virtualisation. Like virtual machines, they have existed for some time, but their widespread adoption is more recent and still rapidly growing and evolving. Containers bring exciting benefits in terms of performance, portability and more agile computing paradigms, but also certain trade-offs, the most commonly acknowledged being their security.

In this talk Kate will summarise the key differences between virtual machines and containers and identify their main pros and cons over a cross-section of applications. I will then look to the future and explore the potential I see to address new and increasingly complex technological challenges with container technology as it continue to mature.


After the presentation and any questions we will open the floor up for a discussion,  if anyone feels like they would like to bring along any ppt’s or links that they want to share for discussion then please bring it along on a USB or mail the team with info and we can share this during the discussion period. Don’t forget – you don’t have to work in the industry or be a geek, this is a group for anyone with an interest in the subject!

Please sign up on our meetup page here MEETUP

Do come along for pre-presentation mingling as we will be there from 6.30pm. As always, we welcome men to our group, but to keep our audience predominantly female, we ask that all men are accompanied by a woman (just add a +1 on the meetup).


The food and hosting is kindly sponsored by regular GGD supporters HP, there is free parking and feel free to mail or comment on the meetup if you need a lift.

Oracle and Bristol GGD talk #52

As promised I am going to try and get a bit more active with the blogs for the GGD’s so heres the first of hopefully many!

We had a great talk last night – kindly hosted by Oracle in their new swish offices, Thom Legget was kindly given the pleasure of managing us as Jude and Phil who set it up had run off to Glastonbury, looking at the mud pics earlier in the day I think I was happier with free wine and pizza and talking Data!  So Thanks Thom!

We had talks from Jen Williams from Networked Planets, Martha King from Knowle West media Centre and Katherine Rooney Bristol City council and managing the Cuncils Open Data work.

The Dinners are only a success thanks to members attending and we had a great turnout last night – we had a lot of interest in the data management, Helen Woodcock was there discussing their free training offer KETL training

Oracle also have a free training offer – we’ll follow up on whats involved there as they are just putting it together.

Katherine Rooney from Bristol City Council’s ‘City Innovation team’ manages the Council’s Open Data work, offered up our members a special free open data institute membership ODI membership

When asked if you are affiliated with a Node, please select Bristol! – It may look just like the normal ODI membership page, but it’s a unique link for the Bristol complimentary membership so you should be able to complete your membership without making any payment.” (i’ve just joined and she’s right it is free!!)

Lastly we introduced Dana who regularly attends our affiliate support group Womens Tech Hubs F3F see the events page WTH events page.  Dana is helping set up the TEDx Bristol event next year and they are looking for speakers and helpers so please take a look TEDx Bristol WTH post

We have next months talk planned – but currently nothing planned for post the summer break, HP are looking to host one but if anyone has any offers for speakers or hosting then please get in touch with us.


Hopefully see you all at the next event
