Please join and try the AWS Hands-on-Lab Workshops Activities for Builders!

At AWS, we consider all are builders. The innovators, the collaborators, the creators. The ones who see what doesn’t exist, and then make it exist. We believe nothing should stand in the builder’s way, and dreams never have to turn off. With AWS, it’s time to build on.. Because we are aiming to build something […]

What is Cloud?

Definition of Cloud? I usually answer this question with this mechanism (from my perspective) You can ask “What”, “Where”, When”, “How”, “Why” to answer that question. What? >> it is collection of IT resources (such as compute, storage, artificial intelligence, function, framework, applications, etc) Where? >> it can be accessed from the internet, so literally […]

These are top 16 Common/Killer Use Cases from VMware NSX for You!

Whenever I pitch about NSX to customer, I always start with the use cases. On-target questioning and in-depth listening to customer’s pain points are important, so we can collaborate together to solve their issues and going beyond that to enhance their innovations. For me, it is not relevant right now to describe the byte per-byte […]

Troubleshooting slow performance on application di atas VMware virtualization

Setelah kita masuk ke dunia IT operation, akan banyak hal-hal operasional yang membutuhkan troubleshooting. Biasanya disebabkan karena slow performance dari sebuah aplikasi. Jika ini terjadi di virtualization environment, maka kita perlu memastikan bahwa infrastructure yang ditangani mampu memberikan jaminan SLA yang sudah kita sepakati sebelumnya. Berikut ini adalah beberapa key area yang perlu diperhatikan untuk […]

Tutorial Instalasi Server DNS, NTP, NFS, iSCSI, VMware vSphere 6.5 (ESXi dan vCenter) di VMware Fusion for Mac atau VMware Workstation for Windows/Linux untuk Virtualization Home Lab.

Melanjutkan posting sebelumnya, kali ini saya akan menulis dalam bahasa Indonesia. Karena saya rasa sudah banyak yang menulis artikel seperti ini dalam bahasa Inggris, tapi jarang dalam bahasa Indonesia. Merayakan launching terbaru dari vSphere 6.5, maka kali ini saya akan melakukan instalasi dan konfigurasi dari komponen tersebut di VMware Fusion MacBook Pro milik saya. Tulisan ini sebenarnya […]

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 […]

Can Not Connect / Error Connecting to iSCSI SAN

Sorry to disturb the tutorial about cloud native application, just a quick note about the troubleshooting. I found an issue today regarding my iSCSI connection to the datastore. All hosts are all having this error when trying to connect to the SAN. This is because I played with my Lab a lot! and tried to […]

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 […]

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 […]

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) […]

Description about My VMware Home Lab in MacBook Pro

I just want to write this, as a personal note for me. Since I always forget when someone ask me this question about my Personal VMware Home Lab that I used to do some researches on-premise. As described earlier in this post: Currently I am adding another Home Lab for my research and demo to […]
