Think of these as different kinds of playgrounds: some are in your own backyard, some are at a community park, and some are a combo of both.
Location: This is like having a playground in your own backyard. All hardware and software are located within your organisation's premises.
Cost: Upfront costs can be high because you need to buy all the equipment and software yourself.
Scalability: Think of this like needing to add more swings or slides to your playground. It can be time-consuming and costly.
Resilience: If something breaks, it's on you to fix it. But you have complete control over security and data.
Maintenance and Management: Again, it's all in your hands, which can be good for control but bad if you don't have a dedicated IT team.
Location: This is like a community park. The hardware and software are hosted by a third-party provider, off-site.
Cost: You typically pay a subscription fee, which can be more budget-friendly as you're not buying the hardware yourself.
Scalability: Easy to scale. Just like going to a bigger community park, you can add more features (like storage or services) with just a few clicks.
Resilience: Usually quite high because providers have resources to ensure uptime and security, but you're trusting someone else to keep it safe.
Maintenance and Management: Managed by the provider, so you don't need to worry about it. But this means you have less control.
Location: A mix of both—some resources are on-site, some are in the cloud. Imagine having a small playground at home but also using the community park.
Cost: Initial setup can be costly, but you have more control over ongoing costs.
Scalability: More flexible than on-premise but can get complex. You can add new features either on-site or in the cloud.
Resilience: Generally high because you have backup options. If one part fails, you can rely on the other.
Maintenance and Management: Can be complicated because you're managing both types. It's like maintaining both your home playground and keeping an eye on how the community park is managed.
So, in a nutshell, on-premise gives you control but can be costly and hard to scale. Cloud is easier to manage and scale but can be less secure. Hybrid gives you a mix of both worlds but can get a bit complicated.
Elon Musk’s internet system is known as Starlink, which is operated by SpaceX. Starlink is a satellite internet service that aims to provide high-speed, low-latency internet across the globe, even in remote and rural areas1. The system consists of a constellation of small satellites in low Earth orbit (LEO) and uses advanced technologies such as phased array antennas and optical space lasers to deliver broadband internet capable of supporting streaming, online gaming, video calls, and more2.
Starlink is designed to be easy to set up with just two steps: plug it in and point it at the sky, requiring an unobstructed view for optimal performance1. It offers a service without long-term contracts, allowing users to cancel at any time1. As of September 2022, SpaceX had launched more than 3,000 satellites into LEO to support the Starlink network3.
The service is particularly beneficial for areas where traditional internet infrastructure is not available or is too costly to deploy. With its growing network of satellites, Starlink is expanding its coverage and capabilities, contributing to the goal of global internet connectivity.
