TL;DR VMs on public cloud don’t provide the same level of control over sizing as on premises VMs, and this can have a number of impacts on how capacity is managed. Most importantly ‘T-shirt’ type sizing can provide sub optimal fit of workload to infrastructure, and the ability to over commit CPUs is very much […]


Originally posted internally 13 Dec 2016, this post marks the end of my journey through the back catalogue: The dust has hardly settled from re:Invent, but today brings the first big public launch since AWS’s big annual event – AWS Managed Services. This will be one of those blog posts that I hope saves me having […]


Originally posted internally 6 Jan 2016: I’d meant to post this before the Christmas break as a guide to things to tinker with over the break, but then I hit the point where pretty much everybody seemed to already be on leave, and it was clearly too late…. So Happy New Year, if you’re not already […]


Amongst the flurry of announcements at re:invent 2016 was the launch of a developer preview for a new F1 instance type. The F1 comes with one to eight high end Xilinx Field Programmable Gate Arrays (FPGAs) to provide programmable hardware to complement the Intel E5 2686 v4 processors that come with up to 976 GiB […]


Amazon have launched Lightsail, a Virtual Private Server (VPS) service to compete with companies like Digital Ocean, Linode and the multitude of Low End Box providers. The service bundles a basic Linux virtual machine with SSD storage and a bandwidth allowance. Pricing starts at $5/month with tiers by RAM allocation. Each larger configuration comes with […]


Late last year AWS launched Private DNS within Amazon VPC as part of their Route 53 service. This allows customers to create DNS entries that are only visible within a VPC (or group of VPCs). It’s also possible to have ‘split horizon’ DNS where servers inside a VPC get different answers to the same queries versus users […]


All of the major cloud providers now offer some means by which it’s possible to connect to them directly, meaning not over the Internet. This is generally positioned as helping with the following concerns: Bandwidth – getting a guaranteed chunk of bandwidth to the cloud and applications in it. Latency – having an explicit maximum […]


At last week’s Ignite conference Microsoft announce a set of new networking capabilities for its Azure cloud described as being ‘for a consistent, connected and hybrid cloud’. The new capabilities include improvements to ExpressRoute, Azure’s Internet bypass offering, availability of ExpressRoute for SaaS offerings such as Office 365 and Skype for Business, additional VPN capabilities […]


At their re:invent 2014 show Amazon launched AWS Key Management Service (KMS), “a managed service that makes it easy for you to create and control the encryption keys used to encrypt your data, and uses Hardware Security Modules (HSMs) to protect the security of your keys”. At launch the service supported EBS, S3 and Redshift. […]


This post originally appeared on the CohesiveFT blog Amazon recently announced the new t2 family of low end instances, which I wrote about on InfoQ. Pricing wise the headline is that the t2.micro is ¢1.3/hr, which is a fair bit cheaper than the ¢2/hr of the t1.micro it replaces. It also has much better performance, and more […]
