Explanation about How CPU Limit and CPU Reservation can Slow your VM (if you don't do a proper sizing and analysis)

In this post, I would like to share about CPU limit and CPU reservation configuration in vSphere ESXi virtualisation technology. Actually those features are great (since the configuration also available in vCloud Director (*it will call the configuration in vCenter)). Those features are great if you really know and already consider on how to use it properly. For example, if […]

Docker Version Manager (DVM) to easily Move between Docker Client Version

Another break-time post from the continuous tutorial about cloud native applications 🙂 Sometimes when we are working in container environment, we found server’s version is not the same as client’s version. So we can not connect to the server. To easily solve this issue, we should install dvm (docker version manager) so we can easily […]

Running your Docker in Production Environment using VMware vSphere Integrated Containers – (Part 2)

Following our tutorial, now we will continue to do the installation and configuration for those components. So, rephrasing previous blog post. By utilising vSphere Integrated Containers, now Developers can use their docker commands to manage the development environments, also functionalities are enriched with specific container management portal (VMware Admiral) and enterprise features container registry (VMware Harbor). System […]

Running your Docker in Production Environment using VMware vSphere Integrated Containers – (Part 1)

In this tutorial, after explaining about running Docker in my Mac. Now, it’s time to move those dockers on your laptop to production environment. In VMware, we will utilise vSphere ESXi as the production grade virtualisation technology as the foundation of the infrastructure. In production environment, lot of things need to be considered. From availability, […]

Running your First Cloud Native Applications using Docker Container in Mac

As previous post, I will elaborate about Cloud Native Applications. But before that, I will post some basic concepts about Docker as the Container technology for Cloud Native Applications approach. Docker is an open platform for developing, shipping, and running applications. Docker enables you to separate your applications from your infrastructure so you can deliver […]

VMware Photon Platform or vSphere Integrated Container

Cloud Native Applications implementation using container technology is hardly to ignore if you want to keep up with this culture of agile and fast innovations. VMware have two approaches to support for this initiative. Either to use vSphere Integrated Container approach or VMware Photon Platform approach. So, what are the differences? In Summary: If you want […]

Physical CPU (pCPU) and Virtual CPU (vCPU) Ratio in VMware vSphere ESXi Environment

I have some testings couple of times about this. In a Business Critical Applications, Telco Workloads Applications (Network Function Virtualisation (NFV)), or High CPU intensive applications (without high up and down intensity of CPU workloads), it is always recommended to do dimensioning of 1 vCPU compare to 1 pCPU. Regardless we have the performance benefit […]

Why do we need to Virtualize our Oracle Database

Usually customer would like to expand the benefits that they already achieved using virtualization (financial, business and operational benefits of virtualization within its operating environment) to another level. For example to Business Critical Applications such as Oracle Database, thereby reaping the many benefits and advantages through its adoption of this infrastructure. Customer aims to achieve […]

Update sequence for vSphere 6.0 and its compatible VMware products

Following our technical discussion regarding upgrade VMware environments, actually I already wrote about this topic in different thread  in this blog. But, I would like to emphasise again by using another KB from VMware. VMware has made available certain releases to address critical issues and architectural changes for several products to allow for continued interoperability: vCloud Connector (vCC) […]
