The Internet of Things (IoT) has grown from an interesting concept to a paradigm that is changing the way individuals and businesses operate in the 21st Century. It is based on connecting IP-capable devices so they can communicate with each other in a variety of ways. They range from automated industrial assembly lines to smart appliances that promise to make life easier and more convenient for consumers.

A common aspect of all IoT implementations is that they make use of large amounts of data collected from network-connected devices. As with most data-centric applications, IoT systems rely on databases to store and process the accumulated information that drives them. MySQL is a valid choice in database platforms when you are designing a system that interacts with the IoT.

“Spark and Ignite can complement each other very well. Ignite can provide shared storage for Spark so state can be passed from one Spark application or job to another. Ignite can also be used to provide distributed SQL with indexing that accelerates Spark SQL by up to 1,000x.”–Nikita Ivanov.

I have interviewed Nikita Ivanov,CTO of GridGain.
Main topics of the interview are Apache Ignite, Apache Spark and MySQL, and how well they perform on big data analytics.

Q1. What are the main technical challenges of SaaS development projects?

Nikita Ivanov: SaaS requires that the applications be highly responsive, reliable and web-scale. SaaS development projects face many of the same challenges as …

In this blog post, I’ll discuss how to use MySQL 5.7 Document Store to track data from Internet of Things (IoT) devices.

Using JSON in MySQL 5.7

In my previous blog post, I’ve looked into MySQL 5.7.12 Document Store. This is a brand new feature in MySQL 5.7, and many people are asking when do I need or want to use the JSON or Document Store interface?

Storing data in JSON may be quite useful in some cases, for example:

• You already have a JSON (i.e., from external feeds) and need to store it anyway. Using the JSON datatype will be more convenient and more efficient.
• For the Internet of Things, specifically, when storing events from …

Are you building an IOT solution and want to know how to store and retrieve your IOT data? Perhaps you're new to database systems and want to learn how to use them while you explore the exciting world of IOT.

This book is the answer for both scenarios; whether you're new to IOT and want to know how to leverage MySQL in your solution or you've wanted to learn more about MySQL, this book will provide many of the answers you seek.

The book also covers how to design your IOT solution around your data. Not only will you learn more about MySQL, but you will also see how best to deploy MySQL in your IOT solution using low-cost computer boards such as the Raspberry Pi, Beaglebone Black, Intel Galileo, and more.

Finally, the book will give you a thorough overview of how data can be augmented and annotated to make it easier to glean the golden nuggets of knowledge you seek while wading through your sensor data. …

Introduction
In my last blog post, Internet of Things, Messaging and MySQL, I have showed how to start your own Internet of Things with Particle Photon board. That implementation is great, but requires constant internet (wi-fi) access as the Particle Photon board does not have any local storage. If you do not have a reliable network access (i.e. in some remote places) or need something really small to store your data you can now use Intel Edison. I’ve even install MySQL on Edison, which makes it the smallest (in size) MySQL server in the world! Other options include:

• Raspberry Pi (my colleague Roel installed …

Personal Projects with the Internet of Things

So you want to do a personal project with the Internet of Things (maybe a home automation or metrics collection or something else)? In this blog post I will tell about my recent experience with this. I will give a talk on this topic at Oracle OpenWord 2015 (Tuesday, Oct 27, 6:15 p.m., Moscone South, 274).

Here is what I did: I was looking for the best place to plant some trees in my backyard. I learned that I need to know how much sun I have in the backyard before planting (some trees need full sun, while others need partial sun or shade). So I needed to measure the sunlight in different spots.

The “old” way of doing it was to use …

A few months ago I updated my profile on LinkedIN, and adjusted my position as CTO and founder of Athoa Ltd, a British company currently active for translation services and events that in the past hosted a couple of interesting open source projects. I simply forgot to disable the email notification to my connections, set by default, and in 2-3 hours I received tens of messages from friends and ex-colleagues who were curious to hear about my new adventure.

Today, I changed my profile on LinkedIN again and have left the email notification set on purpose.

As of today, I join the team at ScaleDB. My role is to define the product and the strategy for the company, working closely with CEO Tom Arthur, CTO …

The Big Data explosion in recent years has created a vast number of new technologies in the area of data processing, storage, and management. One of the biggest names to appear on the scene is Hadoop. In case you need a quick review, Hadoop is a Big Data storage system that takes in large amounts of data from servers and breaks it into smaller, manageable chunks. The technology is complex but at a high level the Hadoop ecosystem essentially takes a “divide and conquer” approach to processing Big Data instead of processing data in tables, as in a relational database like Oracle or MySQL.

1. 12 Months with MongoDB (Worknik) -- every type of retrieval got faster than their old MySQL store, and there are some other benefits too. They note that the admin tools aren't really there for MongoDB, so "there is a blurry hand-off between IT Ops and Engineering." (via Hacker News)
2. Dawn of a New Day -- Ray Ozzie's farewell note to Microsoft. Clear definition of the challenges to come: At first blush, this world of continuous services and connected devices doesn’t seem very different than today. But those who build, deploy and manage today’s websites understand viscerally that fielding a truly continuous service is incredibly difficult and is only achieved by the most sophisticated …
