Following on from my original vRetreat blog post, I thought it would make sense to report on some of the technical IT discussions that happened on the day, For this blog post, I am going to be focusing on the presentation by Darren Swift from Zerto.
So who and what is Zerto? Well, as started on the "About Zerto" page on their website, "Zerto provides enterprise-class disaster recovery and business continuity software specifically for virtualised datacenters and cloud environments."
In simple terms, Zerto provides hypervisor-level replication and automation with no hypervisor vendor-specific lock-in. It provides continuous replication (no snapshots) of virtual machines between hypervisors and replaces traditional array-based replication solutions that were not built to deal with virtualised environments.
I was honoured to have been invited to attend the inaugural vRetreat event in the UK. The event, arranged by Red-Track Ltd, took place at the Porsche Experience Centre at Silverstone on 27 January 2017, and was attended several well known bloggers and virtualisation community members. The day was made possible by Zerto, Veeam and Cohesity who presented on their respective products and upcoming capabilities within their product suites. This provided ample opportunity for those present to discuss several product features and their possible use cases in the world of hybrid and public cloud infrastructure.
Container technology has been around for quite a while now. Most people would by now have heard about Docker, and a lot of people are using Docker. What about VMware Photon? What’s that? Well again, I’d say that it’s been around for a while, however while people have been raving on about Docker and the container revolution, VMware has been working on their own implementation of container technologies as well as products that utilise and integrate with existing container technologies, such as Docker. At VMworld Europe 2016, VMware announced vSphere 6.5 and one feature that has caught my attention in this release (apart from the long overdue vSphere HTML5 Client) is vSphere Integrated Containers, or simply, VIC. At the moment I’m trying to make sense of all these technologies, how (and if) they fit together and where you would want to use each one.
I have identified an issue in Log Insight 2.5 where alerts passed via email or to vROPS contain the following text in the message:
“Notification event – The worker node sending this alert was unable to contact the standalone node. You may receive duplicate notifications for this alert.”
I also confirmed that DNS resolution and reverse lookup functions are working as expected. I was also able to reproduce this issue successfully in a lab environment, with DNS working correctly.
Yesterday I found myself in the middle of a debate on Twitter surrounding DevOps and the future of infrastructure admins. The whole thing was really triggered by a tweet sent by John Troyer where he stated; "Both O'Grady (New Kingmakers) & Chen (Developer-Driven Infrastructure) say "Devs Rool, IT Droolz". How do IT pros adapt?"
I’ve recently published a whitepaper on KEMP Technologies’ range of commercial "LoadMaster" load balancer products that can be found via this post. Now KEMP has introduced a free version to their LoadMaster range of products. This is to provide small businesses and developers with robust and proven load balancing capabilities free of charge.
