GitHub – The Basics 1/2

VMware has been increasing it’s presence and solutions around Cloud Native Applications, in this new world, agility, integration and automation are keys.
More than that, VMware has been contributing to the community with several open source projects like, Photon Controller, Photon OS, Project Lightwave… all of them available at GitHub.

WOW, wait… What’s GitHub ? How do I use it ?

Don’t be afraid we are on this journey together, this post is dedicated to you (myself including), here I’ll cover the basics to start your own Git projects..

Let’s start with what GitHub is all about:
From it’s own page: “GitHub is a code hosting platform for version control and collaboration. It lets you and others work together on projects from anywhere.”
In essence it’s a place where you can store your codes, files, images, maintainig version history for every change you make while others can pull them out, make enhancements and push back to you. Nice !!!

First, you need to create an account at GitHub, I wont cover that, you must be an expert on the art of creating accounts by this time of your life ; )

Don’t forget to install Git tool specific for you O.S plataform;
Althought there’s a GUI tool, the most common used one is the command line, so I'll cover this method here.

Once installed, you will have to configure it, so every time you submitt change to yours or others files, your information will be send along with those changes.

run: git config --global “your_name_goes_here”
run: git config --global “your_email_goes_here”

Now image for a second, if you have to type your user/password everytime you submitt a change to your or others online repository ???  Lukely there’s a way to cache your credentials, so it can be used every time without having to bug you about it.

run : git config --global credential.helper osxkeychain

There’s no output from this command, but next time you interact with a project that requires a password it will ask you once and cache it in keychain for future use.

I believe it’s a lot of content for a single post…. Stay tuned for post 2 where we will actually see it in montion.

VMware is all about choices

During VMworld Las Vegas VMware has announced its partnership with IBM, last week the partnership with Amazon has been announced as well, joining vCloud Air and vCloud Air Networks as a broader Cloud Offering Services.

Just to give you a heads up, this post is not intent to go deeper into technical details, and pros and cons for every each solution, in fact, the idea is to give you a high-level understanding of all these solutions and all the buzzwords around it. Deal ?

Also announce at VMworld Las Vegas, VMware Cloud Foundation is VMware’s unified Software-Defined Data Center (SDDC) platform, targeting private and public clouds. 
Based on a hyper-converged solution, it combines VMware’s industry-leading compute, storage and network virtualization (VMware vSphere, VSAN and NSX) into an integrated solution. But it’s not a simple software bundle that you just purchase and get the same software as if you bought them separately. In fact, the power of VMware Cloud Foundation comes from it’s intelligent and native integrated software stack, VMware SDDC Manager, which automates the design, implementation and life cycle management of the entirely stack.

It was the first available VMware’s Cloud offer, it’s made of an ecosystem of partners, who sells and operates reliable cloud services based on vCloud Director as IaaS, DaaS and DRaaS. As you could imagine with a large number of partners it's not unusual that you find different levels of resources, features, pricing models, and so on among them. This nice search page allows you to find each one them and the services the offer.

It’s basics derives from the same principal and services offered by vCloud Air Network, but on this public cloud offer VMware itself is the one managing and operating it, allowing you to consume cloud resources like Dedicated Cloud, Virtual Private Cloud, Disaster Recovery, Government Services, Object Storage and more.

IBM has been the first vCloud Air Network Partner to enable a hybrid cloud solution based on VMware Cloud Foundation, leveraging worldwide IBM Data Center presence, allowing you great flexibility choosing a location near your company, but more interesting, IBM offers a custom portal that allows you to, on-demand, order new vCenters environments, including the provisioning of physical hypervisors, allows the scale-out of physical resources and the life-cyle of this environment. As it provides you dedicated vCenter, you can use all vSphere features and integration that we all know and love. 

This jointly architected solution that integrates the world’s leading private cloud and the world’s leading public cloud, will allows customers to run any application across vSphere based private, public, and hybrid cloud environments and will provide access to the full range of AWS services.
Based on Cloud Foundation too, it offers a nice management portal with pretty much the same capabilities as described in the IBM offer above, but differently this solution is delivered, sold, and supported by VMware as an on-demand, elastically scalable service.
(available mid-2017)

Now if fo some reason you decided to create your own private cloud on premises, VMware will not leave will behind trying to figure how to integrate all those solutions and ensuring all best practices has been considered by yourself. Thinking about those clients, VMware provides VVD, which is an extensively tested solution path with specific information about product versions, networking architecture, capabilities and limitations, allowing you to build and operate a private cloud, significantly simplify length and complicated design process and shortens provision cycles.  

Nowadays challenge is to manage, monitor and secure your application across multiple, private, public and hybrid clouds leads ensuring identity and access, data security and workload mobility, imagine it’s all possible with a single set of tools that you already know from a central location, well that what Cross-Cloud is all about, eliminating all your operational challenges through a range of Cross-Cloud services.

Now the inevitable question…. Which one is better to me ?
There’s no simple answer for that, and the most spoken sentence comes to play.... "it depends" !!!

My best advice is to make your own homework, trying to identify the variables to this equation.
- what are my companies' business objectives;
- what are my technical requirements; 
- which offer allows workload mobility;
- which offer prevent vendor lock-in;

Once you start building your final list of candidates you will then come to cost aspect of it.
But I have no doubt on my mind that whatever your needs are you will find within VMware the perfect fit for your business.

Good (extensive) reading...

Do you fell that sometimes it’s hard to find the latest fix released ? Well, not anymore, through VMware Patch Download Center you can easily find the patch you have been looking for.

You just need to select the product and version, you could also add some extra filters, like severity level.

Once you click Search, you will see the patches that matches your query, just hit the download button.

At this point just vCenter, ESXi and Cisco Nexus Virtual Ethernet Module are available, but I expect this list to grow.
