Why APIs are Crucial in Microservices Architecture

In order to be able to improve on the fly, many companies have started to use the microservice architecture while they are developing their software suite. Microservice architectures allow you to easily develop, change and maintain your software, but it is not an easy as it sounds. There are many details that need attention in order for the architecture to work properly. One such issue may be the understanding of API and API management for the microservice architecture.

Let’s imagine that we have a shopping application. The client is responsible with the following: the items available, stock, orders and delivery. Each of them is a mircroservice subsequently connected to one or several microservices. Because of this on or several of the issues listed below may appear.

  • Too many microservices directly connected to the client may overload it, along with connection and authentication issues.
  • The variety of services complicates the policy enforcement process since there is no unified policy protocol
  • Data reporting and inter-service communication can be hampered by several clashing data feedbacks

How can APIs and API management help you?

  1. Unified microservices

The first step is to unify several services, which simples the overall complexity of the program and connected services. IT will also increase the speed of the service, which should please consumers.

  1. A more attractive interface

A well-made API will make your service more attractive, since they will not be exposed to the inner workings of the program.

  1. Increased security

Each of the services listed in the example used above may use one of several security protocols. A unified API gateway service will allow all the service to use a similar security protocol, preventing many issues between one service and another. This will help you in the long run, as consumers that encounter multiple security problems (a failed login being the most common) tend to look for alternative services more often.

Easy incremental updates

The unified API also allows you to more easily update all your services, either all at once or each one individually. As your business develops, you will have the freedom to add more services overtime without needing to redesign the whole client from zero.

There are other advantages that further enhance your experience:

  • As it unifies the services, only one connection is needed in order to use all the features it offers.
  • Using automation tools the patches can be easily launched and done.
  • Since it is facile to deploy and install, the gateway needed is also light and flexible. It can run even on modest servers with minimal requirements. They can also backed-up and restored if something goes wrong.

In conclusion, API and API management can greatly improve your business management and development. Feel free to explore several APIs before you choose the one that is best for your needs.

  2. Transfer the package on your device
  3. From your home screen go to Settings/ System Updates/ Local Upgrade
  4. Click on the option, select the ROM file and wait for the installation to complete

The Open Beta initiative allows users to test the ROMs before they are released as official updates, while also allowing the company to sort out bugs at a faster rate, since the users can report freely any bugs that they encounter. After a final version is ready, it will be released as an OTA update for the entire user base. If you have a beta ROM installed you will only get beta updates. In order to enjoy the stable version you will have to return to the standard version.

In order to that you must download a stable ROM package from the official website and repeat the same steps that were used for installing the beta.

If you decide to swap your ROM, backup all your important data as the contents of your phone can be deleted during the installation.

A Brief IoT Processing Tutorial – Apache Nifi 1.7 and MiniFi 0.5

In this tutorial, you will learn the basics of using IoT development by using the DeepLearning protocol. The process involves IoT data reading, Big Data processing and data ingestion in order to track simple events, data processing, flow, conversion and storage. Apache Nifi 1.7 and MiniFi 0.5 are mandatory for data ingestion.

Prerequisites

  1. A Raspberry Pi, to which you add a USB camera, and install Python, Sensor libraries, Java 8, Minifi 0.5, Apache MXNet and the latest patches.
  2. The MiniFi will push files such as JSON and JPEG to the Apache NiFi server. You can also choose to push the data to a Nifi/Kafka cluster instead, as long as they use a HDF 3.2 environment.
  3. The Apache NiFi cluster will push the data to Dockerized API, Hive and HDFS which work in a HDP 3.0 or similar third party IPs.
  4. Nifi and Kafka can be used in conjunction with Schema Registry in order to compile tabular data and JSON GPS data.

I personally prefer to stream data into Apache ORC files and use them in order to compile external data tables

I use command lines in order to create two distinct tables and storage locations. The tables are generated automatically and they are stored at the designated location as ORC locations.

The general command is: ‘’CREATE EXTERNAL TABLE IF NOT EXISTS (insert name)’’

In order to facilitate the processing task, I also create a Hive 3 acid table:

  • create table rainbow acid (add the line between brackets)
  • After it is done I load the data
  • Insert in x acid (where x is the name of the file)
  • Select * from x

I then use the most recent version of Hive in order to sort out and separate data. I hope this tutorial was useful for you and that it will help you to get started in IoT. Cheers!

CoinText Startup Allows Users to Send Bitcoin Cash (BCH) via SMS

A startup called CoinText has developed a solution to send Bitcoin Cash (BCH) via SMS. That would allow the adoption of this cryptocurrency to rise in areas where there is no good Internet connectivity.

CoinText allows its users to send Bitcoin Cash (BCH) via SMS

The CoinText tool is now available and has enabled the first Bitcoin Cash (BCH) transactions via SMS, according to a tweet published by the company on August 31st. CoinText currently offers its services in the United States, Canada, the United Kingdom, Australia, the Netherlands, South Africa, Switzerland, and Sweden, according to the company.

According to the information on its website, CoinText works by using each user’s full number (including area and operator codes) as a unique identifier to create the seed of a new Bitcoin Cash (BCH) wallet. Once a portfolio has been generated, the application provides an API that communicates with a global SMS gateway provider that provides network access and allows coins to be sent via text messages without the need for an Internet connection. CoinText will charge a flat fee of 10 BCH satoshis.

The team warns that the platform does not store any information and depends on some third party services and all transactions are immediately settled in the blockchain. For this reason, they do not recommend its use for storing large quantities of coins.

Sending cryptocurrencies via SMS is not a new method

The CoinText method is something new for sending Bitcoin Cash (BCH) via SMS, but, in the past, similar tools have been developed for sending other cryptocurrencies. For example, in early August, a Californian company called Intuit was able to patent this kind of service for Bitcoin (BTC).

Similarly, an update made by the Samourai Wallet in January included a similar tool that offers the ability to send Bitcoin (BTC) via text messaging, just like CoinText does with Bitcoin Cash (BCH).

Also in August, a startup launched an application that allows its users to send Litecoin (LTC) via Telegram instant messaging app. The Zuluc Republic, the company behind the project, announced that it plans to include the SMS feature.
