  1. Safely Upgrading PAS 2.2 → 2.3 with NSX-T Load Balancers How to upgrade an NSX-T-based PAS 2.2 foundation to 2.3 without downtime Categories:   NSX-T    Operations Manager    BOSH   
  2. How to Install a TLS Certificate on vCenter Server Appliance (VCSA) 6.7 We install a Transport Layer Security (TLS) certificate issued by a commercial Certificate Authority (CA) on a VMware VCSA 6.7 while avoiding several pitfalls. Categories:   vSphere   
  3. Benchmarking the Disk Speed of IaaSes It’s helpful to know the performance characteristics when selecting a disk type for an Infrastructure as a Service (IaaS). In this blog post we describe the results of benchmarking various disk types of various IaaSes, including Amazon Web Services (AWS), Microsoft Azure, Google Compute Engine (GCE), and VMware vSphere. We measure Input/output operations per second (IOPS), read throughput, and write throughput. Categories:   BOSH    Logging & Metrics   
  4. Draft GoBonnieGo: A Simple Golang-based Filesystem Benchmark Program Traditional single-threaded filesystem benchmark programs may underreport results when a slower processor is matched with a fast Solid State Disk (SSD), for increases in single-threaded processor performance have not kept pace with the advent of fast SSDs. In this blog post we present GoBonnieGo, a multi-threaded Golang-based filesystem benchmark program. Categories:   Logging & Metrics   
  5. Deploying BOSH VMs with IPv6 Addresses on vSphere Recent changes to the BOSH software suite enable the assignment of IPv6 addresses to VMs deployed by the BOSH Director in a vSphere environment. In this blog post we describe how we deployed a BOSH Director and subsequently used the Director to deploy a web server with a private IPv4 address and a public IPv6 address. Categories:   BOSH    IPv6   
  6. Draft BOSH deployed to an IPv6 environment on vSphere Recent changes to the BOSH software suite enable the assignment of IPv6 addresses to both the BOSH Director and to the VMs deployed by the BOSH director. In this blog post we describe how we deployed a BOSH Director and subsequently used the Director to deploy a web server, both VMs with only IPv6 addresses, no IPv4. Categories:   BOSH    IPv6   
  7. Maintaining BOSH Directors with Concourse CI and bosh-deployment BOSH directors can be deployed (and redeployed) with a properly built Concourse pipeline and manifests generated by the curated bosh-deployment manifest generation tool. This lightens the burden of keeping BOSH directors patched & up-to-date. Categories:   BOSH    Concourse   
  8. Deploying a BOSH Director With SSL Certificates Issued by Commercial CA A BOSH director is typically deployed with self-signed SSL (Secure Sockets Layer) certificates; however, the director can be deployed with certificates issued by a trusted CA (Certificate Authority). Here’s how. Categories:   BOSH   
  9. Deploy To vSphere NSX-T Opaque Networks Using BOSH BOSH now allows attaching vSphere deployed VMs to NSX-T’s Opaque Networks Categories:   BOSH    BOSH CPI    vSphere    NSX-T   
  10. Why Is My NTP Server Costing $500/Year? Part 3 Running a Network Time Protocol (NTP) server in the pool.ntp.org project can incur $500/year in data transfer (bandwidth) costs. Those costs can be reduced or even eliminated by choosing alternative Infrastructure as a Service (IaaS) providers, modifying the server’s pool.ntp.org connection speed setting, choosing an alternative continent upon which to place the server, and modifying the NTP daemon’s configuration file to rate-limit the clients. Categories:   NTP   
  11. Using the beta BOSH CLI to Deploy an IPv6-enabled nginx Server to AWS Amazon Web Services (AWS) has recently announced Internet Protocol version 6 (IPv6) Support for their Elastic Compute Cloud (EC2) Instances in Virtual Private Clouds (VPCs). In this blog post, we describe using the beta BOSH command line interface (CLI) to deploy a virtual machine (VM) running nginx (a popular webserver) to EC2 with a native IPv6 address. Categories:   BOSH    IPv6   
  12. Leveraging NSX's Features with BOSH's vSphere CPI BOSH, a VM (Virtual Machine) orchestrator, includes the ability to interoperate with NSX, a network virtualization platform, when deploying to a vSphere IaaS (Infrastructure as a Service). This blog post describes deploying VMs as the backend of an NSX Load Balancer. Categories:   BOSH    NSX    vSphere   
  13. How to Customize a BOSH Stemcell BOSH Stemcells are Linux-based bootable disk images upon which BOSH applications may be deployed. This blog post describes a process to customize a stemcell (most often used to troubleshoot stemcell boot problems). Categories:   BOSH   
  14. Updating a BOSH Release Authors of a BOSH Release may want to release a new version when the upstream application is updated. This blog post describes the process of updating a BOSH Release while avoiding common pitfalls. Categories:   BOSH   
  15. Concourse has Badges Use Concourse’s badges to display the health of your project Categories:   Concourse   
  16. Concourse without a Load Balancer nginx is a less-expensive alternative to a load balancer for a BOSH-deployed Concourse server’s SSL termination. Categories:   BOSH    Concourse   
  17. How to Deploy a Multi-homed BOSH Director to a vSphere Environment We explore deploying a multi-homed BOSH Director to a vSphere environment to segregate networks in a secure manner. Categories:   BOSH   
  18. The World's Smallest Concourse CI Server How to deploy a publicly-accessible, extremely lean Concourse CI server. Categories:   BOSH    Concourse
