Amazon Web Services Cloud Storage

My name is Luthfan Rasyad Maulana and this particular blog will be about Amazon Web Services Cloud Storage explained in a video by Eli the Computer Guy with a duration of 57 minutes and 12 seconds. The link can be found -->

AWS Storage is an IaaS Cloud Storage or Infrastructure as a Service instead of SaaS or Software as a Service like for example Office 365, Google Drive, DropBox. The difference is that with Software as a Service like Google Drive, you get to use it from the get go, but that is not how AWS cloud storage works. When you buy AWS Cloud Storage it is just literally storage that you buy to put all you data without any obvious way to connect to it unlike DropBox and Google Drive which is as simple as that. The actual way to send and/or pull data from the storage is something that has to get built. Whether a web application you create will be able to connect to it, or an app from your local computer will be able connect to it etc.

There are many different types of storage options according to specific needs, for example if you need a form of storage that your web application will be able to push and pull data to, that is its own thing, if you need a media application with content delivery network, that too is its own thing, if you need something blazing fast for a database, that is its own thing.

Amazon S3 (Simple Storage Service)

Amazon Simple Storage Service is storage for the Internet. It is designed to make web-scale computing easier for developers. Amazon S3 has a simple web services interface that you can use to store and retrieve any amount of data, at any time, from anywhere on the web. It gives any developer access to the same highly scalable, reliable, fast, inexpensive data storage infrastructure that Amazon uses to run its own global network of web sites. The service aims to maximize benefits of scale and to pass those benefits on to developers.

-Flexible Storage Buckets

-Encryption

-Versioning

-Regions

-Different Prices Based on Availability

1 type of AWS that is recommended by Eli the Computer Guy is S3 Glacier. It is a version of S3 for archiving. It is very very cheap with $0.007 per GB. So 10 GB will cost only 7 pennies, 100GB will cost 7 cents and 1000GB will only cost 70 cents. This is a brilliant idea for backing up encrypted data for back-ups. The downside of it is that it is considerably slow. but unlike a database, archiving would not need that fast of a speed to be useful.

Benefits of AWS Cloud Storage

-Highly Scalable

-Ease of Administration

-Can be cheap

Problems of AWS Cloud Storage

-Expense Based on Use Case

-Allows for stupid disaster recovery design

As far as amazon is concerned, Eli the Computer guy would be safe using their services as long as he himself was going to build the infrastructure out properly. if you don’t do it right you can build very bad infrastructures. if you are not aware of the scale of the infrastructure, it can bankrupt you in a heartbeat. In my opinion, with myself being just an individual, i would not be needing these kinds of services just yet where i would be more than comfortable using SaaS like Google Drive and DropBox which i already am, but maybe in the future if i would need these services for a company that i create than these services would come in handy. I think that is amazing how far technology has advanced and prior to this i didn’t even know something like this existed.

ULASAN 1 - Network Convergence

NETWORK CONVERGENCE

My name is Luthfan Rasyad Maulana and this particular blog will be about Network Convergence explained in a video by Eli the Computer Guy with a duration of 46 minutes and 23 seconds. The link can be found -->

Network convergence is a huge issue in the modern world and could cause you major problems if you do now know what it is. Network convergence is where all types of technology systems are being changed and migrated so they they work on TCP/IP networks instead of their own dedicated infrastructure like cctv's and telephone systems using their own protocols like they used to. This can be a great thing but can face some problems.

Back in the day everything used their own infrastructure. It used its own hardware and protocols. There were 4 silos which are cctv, telephones, PC, and access control. Everything had to have its own infrastructure with its own quirks and problems. Instead of having multiple different silos, network convergence converges all those silos into one. Separate types of cables are no longer needed and ethernet is now used for everything. In a lot of ways this is an amazing thing, you dont have to run multiple types of cables all over a building. One thing from a business stand point is that when you build out an infrastructure, you always have to over-provision. The reason is the flexbility going in to the future and before convergence, it would have been much more of a hassle. All of these devices can now communicate with each other in new and interesting ways.

The things that have to be thought through with convergence are:

-Network capacity --> The speed of the network has to be able to account for the data being used by everyone using the network

-Service capacity --> More load can be weighted on the services being on this convergence and this has to be taken into account.

-Criticality of infrastructure: How critical an infrastructure can be

The problems with convergence are:

-Bandwidth issues --> if the network infrastructure is still the old one, and the amount of devices has multiplied by 4 of 5 times, you can shut down the network very fast even with simply 1 incorrectly configured device.

-Hacking issues --> with the old silos, even if someone hacks into one, they cannot reach the other silos, but now if everything is one on one infrastucture you can have problems with hacking.

-Compliance issues --> with boxed networks before convergence, communication was secure, but with convergence over one network, communication has to be ensure it is encrypted.

-Random issues --> Like overheating network cables. If a lot of power in run through ethernet, heat can start to form and overheat and cause accidents.

Mitigating convergence issues:

-increase network/ ISP Capacity

-Qos

-Bandwidth Throtting

-Parallel Networks

-Pushing Intelligence to the Edge

I think that the more connected the world becomes, the more problems it faces. However, in my opinion, the benefits of a vastly connected world outweigh the problems and we should strive to achieve greater things without fearing the drawbacks. In this modern world something called the IoT(Internet of Things) has been forming and will lead to the ultimate converged world.
