Setting up Read-Only Access to S3 using AWS Identity and Access Management (IAM)

By Imran Ahmed A common problem with a very simple solution. Let’s say that you have an IAM user that you’ve created, and you want to provide that user read-only access to an S3 bucket. An example of this that may be common is for those vendors, such as Newvem, that request programmatic access to your billing data. For beginners, the format and implementation may be confusing or challenging. Many of the basic policies you may attach to a user or group can be found under Policy Templates. These are, however, very limited and tend to tackle access in a very broad sense. Always ...read more … [Read more...]

Setting up Multi-Factor Authentication with Amazon Web Services (AWS)

By Imran Ahmed Introduction Amazon Web Services provides a very robust permissions and policy management system through IAM, or Identity and Access Management. One step further that a corporate administrator can go to help protect some of their most restricted accounts. Multi-Factor Authentication, also known as Two-Factor Authentication, is an added layer or protection beyond the typical username and password. Typical devices utilize secure algorithms to provide the user with a rotating code which they would need to supply in addition to their username and password. Most commonly, this is … [Read more...]

Configuring AWS Auto Scaling for WordPress

In previous posts, I covered the basics of Amazon Web Services, Preparing AWS Services to support our sample WordPress workload, and Installing WordPress in AWS with ElastiCache and S3/Glacier backups.  In this post we’ll look at how to configure an AWS Auto Scaling group of WordPress servers that respond dynamically to the load placed on them by creating new EC2 instances on demand, or spinning down unnecessary instances during low demand to save on operational expenses.  Auto Scaling uses AWS Cloud Watch to monitor AWS components and responds to alarm metrics (CPU utilization, number of … [Read more...]

PCoIP Packet Loss? Don’t Blame the Network!

Several months ago I was called into a new customer to diagnose some odd behavior in their VMware View environment. The organization was struggling with constant disconnects and generally poor performance on their View desktops. When users weren’t being randomly disconnected from their desktops, the users experienced lag when dragging windows between multiple monitors, ‘choppy’ graphics/video, and slow application launching. The problems occurred with local and remote users (both WAN and LAN could be involved).  The customer had done some troubleshooting, worked with VMware Support and the … [Read more...]

Installing WordPress on AWS

Now that we have our AWS infrastructure configured to support a sample WordPress workload (see Part 1 and Part 2 of this series) we can get into installing and configuring WordPress, AWS ElastiCache, and S3 / Glacier backups. Setup NFS Server for WordPress Media Library Our WordPress EC2 instances will be transient – we’ll be using AWS Auto Scaling to spin up and down web server instances as needed.  In a single server setup, WordPress expects a local (ext4) directory (/wp-content) within the web server root directory for storing WordPress content (themes, plugins, media library, images).  … [Read more...]

Preparing Amazon Web Services (AWS) for an Auto-Scaling WordPress Site

Preparing Amazon Web Services (AWS) for an Auto-Scaling WordPress Site In my last article I covered the basics of Amazon Web Services (AWS). Now it’s time for some hands-on configuration. The example I’ll be working with in the next few posts is a WordPress based site. I’ll leverage a bunch of services within AWS to support my site – Route 53 for DNS, RDS (MySQL as a Service), Elastic Load Balancers in front of auto-scaling EC2 instances (monitored by CloudWatch), ElastiCache, Simple Storage Services (S3), and CloudFront. As you can see, this setup will be very different from the shared … [Read more...]

Multipathing Support in vSphere Standard Edition

A customer recently asked me if storage multipathing is supported in vSphere Standard Edition.  The customer had reviewed the vSphere Editions comparison chart at https://www.vmware.com/products/datacenter-virtualization/vsphere/compare-editions.html and saw that Standard Edition did not include the 'Storage APIs for Array Integration, Multipathing' feature.  While the answer was quick and easy, I saw a good chance to provide some detailed information to the customer to better equip them to make an informed purchasing decision and to run their vSphere environment in the long run.  So what is … [Read more...]

Deploying Linked-Clone Desktop Pools Using PowerCLI

By Suhem Parack Deploying pools can be done using the VMware View Administrator. The Add Pool wizard in the Administrator takes us through a series of steps which include user assignment, pool Identification, provisioning settings, advanced storage options etc. (refer to the figure below). In this article we will learn a different approach to deploying pools - using a powerCLI cmdlet. In order to do deploy pools using powerCLI cmdlets, we will make use of the Add-AutomaticLinkedClonePool cmdlet. The general syntax for the Add-AutomaticLinkedClonePool is: ...read more From: … [Read more...]

VMDK File restores using Veeam – Side-by-side access

By Rob Daniels Veeam is a pretty awesome tool for doing full VM and file-level backups of VMware vSphere VMs. Every once in a while, however, you might try to do a restore that is a bit out of the ordinary. One such scenario is when you want to do a full restore of the VMDK files (descriptor and flat) and then mounting the drive alongside the original disk on the original virtual machine. You might want to do this so you can compare files between the current copy and the restored VMDK. When you attempt to mount the restored VMDK, ...read more From: Clearpath Solutions Group Blog … [Read more...]
