have you ever considered that the data you send and receive every day are stored in the virtual world?
well, irfan siddiqui, a silicon valley cloud expert, recently explained in a cloud computing session that cloud computing is akin to renting an online storage platform for a specified period, requiring both time and money.
imagine three cloud service models:
infrastructure as a service (iaas)
think of this as renting building blocks, where the blocks represent servers, storage, and networks.
platform as a service (paas)
imagine buying a pre-built house with basic furniture. while you can customize it with your belongings, the platform handles the main setup. this is ideal for developers focused on building apps rather than managing servers.
software as a service (saas)
picture a fully furnished apartment ready for immediate occupancy with just an internet connection. this is best suited for those who need tools without worrying about maintenance.
now, for another way of understanding, you can think of where you store your college stuff:
public cloud
similar to everyone using the same storage facility, it is less secure and private.
private cloud
comparable to having your own personal secure storage, though it comes with a higher cost.
hybrid cloud
think of this as having both a storage facility and your own lockers. you can choose where to store items based on their importance, whether public or private.
at the end, he introduced us to ci/cd, or continuous improvement. to understand this, you can imagine a production line where new app versions are regularly built, tested, and released automatically. this process makes the software development smoother and faster.
cloud security
also, we had a glance at how ensuring strong security in the cloud is really important, and he also thoroughly talked about ways to make it secure. he focused on different plans and structures to guarantee strong security in the cloud, highlighting the idea that it’s a joint effort between the service provider and the user.
