What’s behind the Virtual Machines?

Are Virtual machines making our world more virtual?

These days virtual machines are running everywhere on the internet, from Microservices to big modules of code running on these virtual machines. We might not know the difference between an application running on a single server or multiple parts running of the same application running on multiple instances of virtual machines, that is the best part about virtual machines. We might not get the difference, but they will make us get the most of our hardware resources.
Virtual machine is hardware-level virtualization, a VM provides a real computer emulation and are implemented using software emulation programs. The end user gets the same experience of an operating system hosted on physical hardware with a virtual machine running on a machine. Virtual machines use the hardware more efficiently and increases the productivity than a single OS running on a dedicated hardware. Multiple VM running on the same hardware can perform different jobs at the same time can effectively improve resource utilization.

A virtual machine monitor (VMM) or a Hypervisor is a program that runs on a machine and helps the host in creating multiple virtual machines that can be run simultaneously, pooling all the resources of the host machine and sharing among the virtual machines. A Hypervisor can manage multiple instances of different types of operating systems like MacOS, Linux or Windows, running on multiple instances in a single physical hardware all at the same time. Hypervisor will manage the distribution of CPU, memory, bandwidth or disk space among those instances. Regardless of the type of hypervisors, virtual machines and the guest operating system will work without any difference.

There are two types of Hypervisors as listed below: Continue reading

Salesforce Deployment Tools

A typical development process requires building, testing, and staging before releasing to a production environment. During this development cycle, one might migrate many times, either to keep development organizations in sync or to move changes through development organizations toward production and this is what we call Salesforce deployment.

Salesforce deployment is the migration of metadata from one Salesforce organization to another. If you are looking to enhance your Salesforce DevOps (Continuous Integration and Continuous Deployments) practices, this blog could get you started with the basics.

There are number of deployment tools available each having its own pros and cons. Some of them are listed below:

Is Race Condition a myth in Salesforce?

Since the introduction of the concept of multi-threading, there has been a drastic change in the way we code. Now multiple threads run in parallel, hence many tasks can be performed at the same time.

Salesforce too adhered to this concept taking a step forward in its endeavor and provided a multi-threaded environment.

But everything has its pros and cons and so did parallelism. Though it completely changed the way programs are executed but brought with it a new concurrency bug what we call as race condition.

When does it actually occur?

Race condition occurs when two thread operate on same object without proper synchronization and there operation interleaves on each other. Continue reading
