How to add a Read-Only user in Bosh

Recently, a customer came up with a request on how they can create a user with less privileges in bosh environment to run any curl queries as in here. In this blog post, we will see how to add a read-only BOSH user who has read access to the director but does not have admin access to deployments.

#SQLServer Read-Only Routing for Availability Groups in Always On.

Not too long ago, I had a conversation with a friend about how SQL Server Always On Availability Groups and how they could be configured for Read-Only routing. This is a typical scenario when folks want to leverage their secondary replicas (nodes) for read-only workloads.

We interrupt you usual programming blog to discuss (complain) about Windows 10. 

I updated my computers to Windows 10 last week after hearing so many good things about it. After spending hours customizing the privacy settings, appearance, and making sure all of my applications actually work, I starting getting used to the new OS and actually began to like it. 

Until I restarted my laptop this morning. 

Um ponto importante. O requisito para parte de configuração de IP estático da interface de gerenciamento do Host também se estende para o seu ambiente de storage. Então, se você possui um storage, esse storage precisa ter endereçamento IP fixo.

Embora, não seja uma restrição técnica, que você tenha um storage compartilhado para criar um Resource Pool, as vantagens de um Pool, como por exemplo, a possibilidade de dinamicamente mover uma máquina virtual entre os Hosts do Pool somente está disponível se o Pool tiver pelo menos um storage compartilhado.

Sendo assim, se possível, adie a criação do Pool do XenServer até que você tenha um storage compartilhado. Uma vez que o storage comartilhado é adicionado, a Citrix recomenda que você mova as máquinas virtuais existentes, que estão rodando no disco local do XenServer, para esta área de storage compartilhado. Isso pode ser feito através do comando xe vm-copy ou através do XenCenter.

Let’s assume I have some data that once created, never again has to change. I have copied this data to an SSD and then re-mounted the file system as read-only and leave it that way from now on. Will doing so increase the lifetime of the SSD?

I am looking for more than a simple “yes, reading does not matter – only writing to…
