Rebuilding An OpenStack Instance and Keeping the Same Fixed IP

By | General | No Comments

OpenStack and in particular the compute service, Nova, has a useful rebuild function that allows you to rebuild an instance from a fresh image while maintaining the same fixed and floating IP addresses, amongst other metadata. However if you have a shared storage back end, such as Ceph, you’re out of luck as this function is not for you. Fortunately, there is another way. Prepare for the Rebuild: Note the fixed IP address of the instance that you wish to rebuild and the network ID: $ nova show demoinstance0 | grep network | DemoTutorial network | 192.168.24.14, 216.58.220.133 | $ export FIXED_IP=192.168.24.14 $ neutron floatingip-list | grep 216.58.220.133 | ee7ecd21-bd93-4f89-a220-b00b04ef6753 | | 216.58.220.133 | $ export FLOATIP_ID=ee7ecd21-bd93-4f89-a220-b00b04ef6753 $ neutron net-show DemoTutorial | grep ” id ” | id | 9068dff2-9f7e-4a72-9607-0e1421a78d0d…

A Year of OpenStack

By | General | One Comment

In late 2013 we looked around the company and asked ourselves the questions any management team has to ask: what are we doing, where do we need to be, and what’s holding us back from getting there? Because Anchor had grown organically across many years, our internal procedures for infrastructure management were spread across a number of tools that weren’t scalable and efficient enough to keep up with the demands of new sales. Furthermore, they weren’t compatible with a product-based self-serve future. There are a number of pieces to addressing that, but certainly it would be tremendously useful to have API-driven software defined infrastructure. The recommendation, universally, was that we needed to consider OpenStack. We were astonished at the degree of rigour and testing that had gone into vetting changes (since the beginning, there have been no un-gated…

Merry Christmas from all of us at Anchor!

By | General | No Comments

2014 has been another amazing twelve months for Anchor, as well as our partners and customers. As you can see, there are now more heads than ever in our seasonal cartoon — and that’s before you count the half-dozen wonderful SysAdmins on our US support team! Anchor continues to grow rapidly to support our exciting future plans, and stand ready for an even stronger 2015. We’re continually looking for new ways to improve our services, so I’m pleased to say we have plenty of exciting developments due to launch in early next year, designed to make working with Anchor even more frictionless and rewarding. These include the full release of our OpenStack cloud and the launch of a new automated infrastructure service called Fleet that promises to change forever how…

AnchorCloud: Thoughts on Pricing Models

By | General | No Comments

The Engineering group has spent much of the last six months developing Anchor Cloud, an infrastructure-as-a-service platform built on OpenStack to offer our customers access to public cloud services in addition to our traditional managed VPS hosting. Instant, on-demand API access to instance provisioning, storage allocation and network management deserves an equally flexible and high-resolution pricing model, and a metering system to support it. Something we’ve been thinking extensively about is how we can best help users assess their infrastructure costs. We think that an invoice detailing (and demanding payment for) your usage over the last month as 256 hours of instance type x and 100 hours of instance type y, while technically accurate, often isn’t the best way of helping users understand where their cost-centres are and how they…

OpenStack – the open cloud

By | Cloud Computing | No Comments

No one likes vendor lock-in. It’s an artificial limitation on technology, designed to benefit the vendor, not the customer. The restrictions may seem insignificant on day one, when the technology may appear to be the best option currently available. But the world keeps spinning and technology keeps evolving, until you’re stuck with a platform that cannot appropriately adapt to suit your new situation without considerable expense. The big, proprietary public cloud vendors of today didn’t invent vendor lock-in, but they certainly know how to work it to their advantage. Cloud Computing isn’t owned by anyone. Companies locked into a proprietary cloud service lose the flexibility  needed to make good business decisions; making vendor lock-in a real threat to your competitive advantage. What might put you ahead one day can hold you back the…

Why OpenStack matters

By | Cloud Computing | 2 Comments

I’m excited about OpenStack. “But you’re a cloud computing nerd anyway,” you say. “Why should we care?” I’ve worked in a few cloud businesses over the years in both London and Sydney, watching cloud computing evolve from niche technology to mainstream buzzword. So, yes I can get disproportionally excited about things that may seem boringly technical and nerdy to others. You’re probably not that interested in the capabilities of an Intel 12 core Xeon E5-2697v2 CPU, for example. But I think OpenStack is different, and something all businesses should be aware of, because it’s going to change the way you manage your business data and hosting. This open source cloud platform is on the cusp of disrupting the cosy, established world of the proprietary cloud providers, just as they themselves…
