What is AWS SNS?

Inside the Amazon Web Services, SNS is one of two services that deal with sending notifications.

SNS stands for Simple Notification Service, and is the name that best defines its function: sending notifications to subscribers quickly and reliably.

How does SNS work?

SNS is a completely unattended and managed service, which operates in high availability, and in a safe and durable manner.

The main advantage of SNS is that we do not need to know anything about its structure or operation, since it is designed so that our only job is to integrate our application with the SNS API , and SNS is responsible for all message distribution work.

In its most basic structure, we only need to create a Notification Theme (a subject on which we want to send messages, such as “Errors”, to warn of system errors), and to subscribe the points that will receive the notification. These points can be of different types:

  • HTTP
  • HTTPS
  • Email
  • Email-JSON
  • Amazon SQS
  • Applicación
  • AWS Lambda
  • SMS

What are the costs of SNS?

SNS is a service designed for the mass sending of messages that, like the rest of AWS services, has a very low cost, based on the volume of messages sent.

In addition, the free AWS layer for SNS includes the first million messages, which will be more than enough for basic uses of the service.

It is important to clarify that the sending of messages via SMS if it has a different cost (is charged for each SMS sent), due to the characteristics of this type of service.

 

Create an Amazon AWS account

The process of creating an account in Amazon AWS is very simple, and includes a very innovative verification system that can give us some headaches.

For those who want to create an account, here we show you the steps, which begin by opening the address in our browser:

https://aws.amazon.com

From here, in the upper right corner, we will see an orange button that says “Create an AWS account”, that we must press.

Create AWS account, step 1
Create AWS account, step 1

The first thing Amazón AWS asks us is the data that we will use to access our account, which must be related to a valid email account.

In addition, we will have to indicate the name of the account that we want to use, which must be unique (usually it will be our name or that of the company).

Create AWS account, step 2
Create AWS account, step 2

After indicating the data of the account, they will ask us for our personal data, used for contact and billing.

It is important to note that the address field must be indicated in the form Street, PO Box, Company name, and in the lower field will be where we indicate the characteristics of the street (Floor 4, door 2, north staircase, etc). We do not have very clear the reasons for this, being that afterwards they ask us again for the postal code, but we must be alert in case it could give problems with the billing information.

Remind you that the data must be real and reliable, to avoid legal problems.

NOTE: We must have the telephone number that we indicate by hand, in order to make the verification.

Create AWS account, step 3

The next step is to indicate a credit card (which has to be valid and be active), although that does not mean that we will incur any charge (they will not do so if we do not exceed the limits of the Amazon AWS free layer).

We must also indicate if we want to use our contact address for the realization of the invoice, or if we want to indicate new data.

Create AWS account, step 4

Now that Amazon has our data, they will verify the phone number through a very interesting system.

First, they will show us a code on the screen, and then they will call us at the telephone number we have indicated, and we will have to enter the code with the telephone keypad.

Create AWS account, step 5

The last step we must complete is to indicate the type of support we want. Although it can lead to confusion, no service plan is indicated here, only the support plan (the speed and way in which Amazon will solve the possible problems that we have).

In general, we will indicate the Free Plan, since it is sufficient for the normal use of our accounts.

Create AWS account, step 6
Create AWS account, step 6

With this, we have our Amazon AWS account created, and we will be redirected to the access page, where we can access with the created data.

Create AWS account, step 8
Create AWS account, step 7

Once we have logged in, we can see in the alert area that we have access to the free AWS layer.

What is the cloud?

Although the concept of Internet cloud has been with us for almost 20 years, it has not been until relatively recently that it has begun to reach all areas, it is now common for cloud services to be offered in environments that are not technical in nature, where before it was impossible.

But … What the hell is “The Cloud”?

Understanding the concept Cloud …

What is meant by the Cloud is no more than many computers working together and providing services on the Internet. It’s that simple. It is not a new concept (although technically it is more advanced) nor is there anything special about it. The Cloud are only the computers of others.

Going into more detail, the cloud concept is a step forward in order to have resources that were previously unthinkable, in much more advantageous conditions, and above all in a much simpler way, which has facilitated its progress.

The Cloud is …

  • A more optimal cost: By paying only for what you use, the costs are reduced, since you can expand or reduce the services you use if you need them.
  • Dynamism: The resources that we use in the cloud can adapt according to our interests, even automatically. Thus, we can adapt to higher workloads without our service suffering, or reduce resources (and cost) in times of less work.
  • Ease: All Cloud services are designed to be used by people who do not have to have a very technical profile. Most services can be configured and adapted with a normal web browser.
  • Security: When using standardized services and managed by specialized providers, its use is safer. In addition, the Cloud even allows us to replicate our services among several countries, in the prevention of major catastrophes.

The fundamental basis of the Cloud is to optimize Internet resources, make them easier, accessible and safe even for the most complex processes, saving costs and energy in the process.

The Cloud is not …

  • A program that we sell to keep our files.
  • A web page to manage our invoices.
  • A dedicated server or VPS that charge us for hours.

While it is true that these services can be hosted in the cloud, when they offer us they are not offering us to work in the cloud, they only offer us a service that may or may not be related to it.

When the concept of Cloud began to become popular, there were many suppliers who wanted to get on the bandwagon to make money with a concept that was still not well understood. The term Cloud became one of the most important SEO terms, although in reality what they offered was not a real cloud, but the same infrastructures that were already available before. Luckily, little by little the concepts are clarified and it becomes more difficult to sell something that is not.

If you want to know more about the Cloud, you can go through the pages of Amazon AWS or Google Cloud, which are the main references of computing in the cloud.
