Twenty years ago I started my professional career working in a niche field of IT called Geographical Information Systems (GIS) – basically mapping systems. This is an area where Big Data was prevalent, long before the term was officially coined, GIS covered a range of concepts from satellite imagery and aerial photography processing to geo-demographic data analysis, address cleansing and geocoding to routing analysis, spatial algorithms and finally to publishing maps & associated data.
Google and Microsoft Bing have recently commoditised a lot of the publishing aspects of background mapping data, but the need for analysing and publishing an organisation’s own geographic data is as important today is it has ever been.
Historically, Application Performance Management (APM) and GIS have never made good bedfellows mainly due to the effort required in deploying APM. At a recent conference I spoke to a GIS developer who stated they had no interest in APM because “they work in GIS.” Upon further questioning, this GIS developer acknowledged processing and accessing these large datasets is complicated and it’s slow and that’s “just how it is.”. So I challenged this and decided to demonstrate AppDynamics on GeoServer, an open source mapping server written in Java that allows users to share and edit geospatial data.
Within a few minutes of installation, AppDynamics automatically detected key transactions such as publishing a map layer.
Taking this a step further, we looked at how AppDynamics can help a system administrator understand which parts of their service is accessed most and which components are the slowest (in this case average response times for publishing mapping datasets).
In the race to prove innocence, the challenge is to be able to determine whether any slow service calls were due to the end user or consumer of a service rather than the service itself — to understand if users are doing something you did not expect. For example, they could be pulling back too much data from the service (this applies to any system dealing with data).
In the case of mapping systems, AppDynamics can capture the bounding box representing the coordinates used to outline and return an area of interest, if the area of interest retrieved is too large and that leads to a slow transaction, then it’s likely a system administrator is allowing users to pull back too much data in one go:
If an administrator does see a slow down in the service they can drill into the service to isolate where performance problems occur. Problems in this type of application can manifest themselves in coordinate conversion, vector data reading (roads, rivers & buildings), database queries, grid handlers (reading image files such as satellite and aerial images), writing to an image file:
System administrators and owners can improve their application or data processing times by identifying bottlenecks. The following example shows how an address lookup service was sped up from processing 60 calls per minute taking a second each, to more than 700 calls per minute taking less than 50ms.
AppDynamics for Databases identified the cause of the slowness as the spatial query used to query the postcode, without an index it went from querying 1,684,930 rows…
To just 5,976: -
Tuning this query led to a tenfold performance improvement!
“Software is eating the world” [Marc Andreessen] and ensuring your application or service is performing is key.

How do APIs and IoT relate? The answer is not as simple as merely adding an API on top of a dumb device, but rather about understanding the architectural patterns for implementing an IoT fabric. There are typically two or three trends: Exposing the device to a management framework Exposing that management framework to a business centric logic Exposing that business layer and data to end users. This last trend is the IoT stack, which involves a new shift in the separation of what stuff happens, where data lives and where the interface lies. For instance, it's a mix of architectural styles ...

We certainly live in interesting technological times. And no more interesting than the current competing IoT standards for connectivity. Various standards bodies, approaches, and ecosystems are vying for mindshare and positioning for a competitive edge. It is clear that when the dust settles, we will have new protocols, evolved protocols, that will change the way we interact with devices and infrastructure. We will also have evolved web protocols, like HTTP/2, that will be changing the very core of our infrastructures. At the same time, we have old approaches made new again like micro-services...

Scott Jenson leads a project called The Physical Web within the Chrome team at Google. Project members are working to take the scalability and openness of the web and use it to talk to the exponentially exploding range of smart devices. Nearly every company today working on the IoT comes up with the same basic solution: use my server and you'll be fine. But if we really believe there will be trillions of these devices, that just can't scale. We need a system that is open a scalable and by using the URL as a basic building block, we open this up and get the same resilience that the web enjoys.

We are reaching the end of the beginning with WebRTC, and real systems using this technology have begun to appear. One challenge that faces every WebRTC deployment (in some form or another) is identity management. For example, if you have an existing service – possibly built on a variety of different PaaS/SaaS offerings – and you want to add real-time communications you are faced with a challenge relating to user management, authentication, authorization, and validation. Service providers will want to use their existing identities, but these will have credentials already that are (hopefully) i...

Container frameworks, such as Docker, provide a variety of benefits, including density of deployment across infrastructure, convenience for application developers to push updates with low operational hand-holding, and a fairly well-defined deployment workflow that can be orchestrated. Container frameworks also enable a DevOps approach to application development by cleanly separating concerns between operations and development teams. But running multi-container, multi-server apps with containers is very hard. You have to learn five new and different technologies and best practices (libswarm, sy...

The Internet of Things is a misnomer. That implies that everything is on the Internet, and that simply should not be - especially for things that are blurring the line between medical devices that stimulate like a pacemaker and quantified self-sensors like a pedometer or pulse tracker. The mesh of things that we manage must be segmented into zones of trust for sensing data, transmitting data, receiving command and control administrative changes, and peer-to-peer mesh messaging. In his session at @ThingsExpo, Ryan Bagnulo, Solution Architect / Software Engineer at SOA Software, focused on desi...

While great strides have been made relative to the video aspects of remote collaboration, audio technology has basically stagnated. Typically all audio is mixed to a single monaural stream and emanates from a single point, such as a speakerphone or a speaker associated with a video monitor. This leads to confusion and lack of understanding among participants especially regarding who is actually speaking. Spatial teleconferencing introduces the concept of acoustic spatial separation between conference participants in three dimensional space. This has been shown to significantly improve comprehe...
