This post originally appeared on the CohesiveFT blog Want to do more with your AWS Virtual Private Cloud (VPC)? We have 10 ways you can enhance cloud networking with our virtual appliance, VNS3. First, a quick background on the product: VNS3 creates an overlay networking on top of AWS infrastructure. This allows you to control security, topology, addressing and protocols […]


Amazon have introduced T2, a new class of low cost general purpose instances for EC2 intended for workloads that don’t drive consistently high CPU usage. At the low end t2.micro offers higher performance, more memory (1GiB) and a lower cost (1.3¢/hr) than the previous t1.micro. The T2 class also offers small and medium sizing with 2GiB […]


Since I started using Amazon EC2 as a web proxy I’ve found that I’m exploiting it pretty regularly. Every time that I see one of those ‘you can’t access that content from your country’ type messages I have a choice. I can give up and move on, or I can fork out 2¢ to spin up […]


I’ve been meaning to try this out for some time, and my recent trials with Amazon’s US Kindle Store prodded me into action. The theory Popular SSH clients (like OpenSSH and Putty) have features that allow tunneling. Amazon Machine Images (AMIs) normally have some way of being administered over SSH. So… start up an EC2 […]


After some reflection on my recent series of posts about Paremus ServiceFabric on EC2 I realise that I never provided a high level commentary on what each of the moving parts does, and why they’re important. Paremus ServiceFabric – this is a distributed OSGi runtime framework. The point is that you can package an application […]


I spent a couple of hours tinkering with this over the holidays, but mostly put it down and got on with eating, drinking and being merry. The first breakthrough was that ContextCubed just worked once I had the right Ruby Gems installed (and in fact day 5 had got me to within one line of […]


Between snow, getting some prerequisite scripts and docs a bit too late and various other stuff getting in the way, there hasn’t been too much progress today. I think I have everything set up to launch a complete cluster of Atlas agents in the sky, and get them to attach to the overlay VPN and […]


The multicast woes are now behind me (thanks Dimitriy), and I now have a fabric that spans my home network and EC2. The problem with multicast turned out to be firewall related, and the simple fix was: /sbin/iptables -I OUTPUT -o tun0 -j ACCEPT /sbin/iptables -I INPUT -i tun0 -j ACCEPT Tomorrow I’ll try to […]


I didn’t get to spend my full attention on this over the last couple of days, and somewhat as expected I’ve run into trouble with multicast. Right now it seems that whenever I put a node into the VPN overlay network it stops being capable of doing multicast. I’ll report back once these issues are […]


I’ve known the chaps at Paremus since shortly after they set up shop, and I’ve watched the evolution of ServiceFabric since its earliest days. Since it has all the makings of a killer PaaS offering I thought I’d sharpen up my practical cloud skills by getting it running on EC2. The first challenge is that […]
