From social media to currency reinvention, digitalization has taken the world on many adventures indeed. However, though businesses and consumers have been enjoying the perks involved, expectations keep increasing from the world of developers.
Competition in the software industry is tough, and in this environment, smaller SaaS businesses have to leverage every advantage they get to survive. But costs, especially hardware expenses, are at an all-time high. How do they ensure their solutions are scalable and applicable to operating systems like iOS, except by investing heavily in expensive Apple devices? The answer to this lies in the fascinating concept of virtualization.
What Are Virtual Machines?
Virtual machines are essentially computers that are not dependent on hardware. They simulate the environment of a computer and can host their own OS and run applications. In other words, you can make a virtual machine copy the environment of the device you want to test your application on without investing in the device itself!
These machines are so helpful that companies like Apple themselves have introduced simulators of their iOS to make testing accessible to all. However, much more sophisticated options exist in the market: you can simply go through Corellium vs iOS Simulator to see one such excellent alternative.
Why Are Virtual Machines Useful?
Such virtual machines have proven themselves as game-changing due to multiple reasons:
1. No Additional Hardware Costs
Arguably, the most significant advantage of virtual machines is that they have enabled developers to test their work across multiple devices and operating systems without purchasing additional hardware. This has made testing much more accessible, leading to the creation of flexible solutions.
The benefit is especially pronounced for small businesses that would not have been able to scale their software solutions to match the cross-platform adaptable software of larger corporations that could purchase multiple hardware with unique operating systems.
Additionally, having less hardware means spending less on HVAC or cooling systems and electricity bills. All in all, the savings are as profound as the scale of your operations.
2. Fewer, Efficiently-Utilized Servers
As you implement virtualization, you enable one single server to host multiple virtual machines that can have different OS and applications. Instead of having multiple devices, each of which is not working at its total capacity, you’ll have one or a few more servers, each running at its max. This will also optimize the work of the IT personnel, and they will be able to maintain a consistent server environment across all VMs instead of going device-by-device to check for updates and perform administrative tasks.
3. Safe Testing and Operations
Virtual machines provide developers with a safe environment to test their apps and codes. Any malfunction stays contained within the VM, isolated from the rest of the device’s software and hardware. This remains true for malware and viruses as well. Apps can be tested rigorously without fear of crashing down entire devices and servers.
Unlike physical systems, disaster recovery is straightforward in virtual systems: you can simply replicate the affected machine or have an untouched clone ready before you begin testing. Organizations that use VMs do not need to host their physical servers at offsite locations to protect themselves against disasters either: server replication in the cloud suffices as a backup.
The increasing accessibility to virtual machines and simulators has revolutionized the workings of businesses and developers. Not only has it led to a decrease in expenses due to reduced reliance on hardware, but it has enabled better tests to be conducted, allowing developers to create apps that are flexible and work across a multitude of operating systems. One can only imagine what exciting innovations this concept will enable in the time to come.
