A Comprehensive Guide To Continuous Deployment

Continuous Deployment is the practice of releasing software on production servers continuously in an automated manner. Before a software is released, it needs to be thoroughly tested for ensuring that it is free from any bugs and errors. In the case of continuous deployment, the testing is done by using a testing software instead of manual testing. If the code is found to be free from errors, it is automatically deployed. The automation of the release of the software helps software development organizations in ensuring that the software updates reach the end-users as soon as possible with a minimum lag time.

One of the primary requirements for continuous deployment is to implement a series of other automated programs that can pull the software seamlessly through later stages of development into release. These stages of development include compiling and validation of source code, reviewing the code, unit testing, integration testing, packaging the application and user acceptance testing.

How Is Continuous Deployment Different From Continuous Integration And Continuous Delivery?

Continuous deployment takes continuous delivery a step further, which is generally perceived as furtherance of continuous integration. In order to understand the difference, it is important to understand the terms individually:

  • Continuous Integration: It is a technique that continually merges the source code from different developers into a shared mainline. This helps in avoiding cataclysmic merge conflicts as new source code is regularly added by various developers.
  • Continuous Delivery: This technique adds a step to continuous integration. It takes the merged code and conducts the necessary tests to ensure that the code is error-free. Thus, in this technique, the code is written, tested and pushed into a production-like environment. The software stays in the holding area until a developer manually pushes it for deployment.

Continuous Deployment reduces the hold time of continuous delivery by taking it a step further. Once the software code is created, tested and pushed into the production-like environment to see how it would perform in the real-time environment; the code is deployed automatically without any manual interference.

Stages Of Continuous Deployment Pipeline

  1. Deploy To Production: In this step, developers need to deploy the software in a production environment without releasing the functionality to end-users. Also, it is important to implement a system that allows you to toggle between the old & new versions.
  2. Verify: During this stage, various tests are performed including user acceptance, stress test, performance test, etc.
  3. Monitor: Monitor the deployed code as per your business metrics to gain insights for strategic business outcomes. Make sure that the code works as desired in the production environment and make the changes as required.
  4. Respond & Recover: After the software is released, it is important to keep a check for unforeseen issues. Manage a system for proactively detecting problems before they are detected by end-users and recover from these problems by providing fixes or patches.

What Makes Location Tracking A Privacy Concern

Undoubtedly using location-based services like Google maps, taxi services, etc. has made our life easier, however, location tracking or geo-tracking poses some real privacy threats as well. In order to understand these threats, it is first important to understand how this data is collected.

How Is Your Location Tracked?

Location is tracked via your devices such as a laptop, mobile phones, tablets, smart-watches, smart jewelry, etc. In the case of a computer, your IP address can be used to track your location. If you are using a mobile device, the location is tracked via GPS, cellular tower data, Wi-Fi signals, and Bluetooth beacons.

A number of popular apps also track your location such as Google Maps, Facebook, Yelp, Uber, dating apps, etc. Some apps may track your location even after you have turned off location tracking in your mobile settings. A common example is Facebook. The app can track your location by your city mentioned in the profile or check-ins.

Additionally, information about your location is also revealed by the metadata attached to your photos. Most mobile phones and digital cameras embed information such as GPS coordinates or Geotags when you take a photo. When such photos are posted on a social media profile, the embedded information is also shared along.

What Kind Of Information Is Revealed By Location Tracking?

Location tracking can be used to disclose a variety of information:

  • Where do you live
  • Your financial status based on where you live
  • Your place of work
  • The regular route of travel
  • Frequently visited stores
  • Your real-time location
  • If you are on a vacation and where are you staying

These are some common types of information that can be disclosed by location tracking.

Privacy Concerns Caused By Disclosure Of Such Information:

  • Stalking & Harassment: Availability of detailed information about your location increases your risk of being stalked or harassed. If a stalker knows your frequently visited places, he can easily identify a place and the best time to confront you.
  • Robbery: Burglars can get hold of sufficient information about you by eyeing your location tracks. This enables them to know when you won’t be home or if you follow a secluded path to your work. Discloser of such private information puts you in a danger.
  • Contextual Advertizing: Contextual advertizing is a rising problem among social media users. Marketing professionals pay a high price for access to personal information such as location data of individuals. This helps them in understanding the user behavior to modify their advertizing campaign accordingly. This has led to a rise in the number of cyber-criminals trying to track the location of individuals for building databases that can be sold to organizations.
  • Frauds: Fraudsters can gain access to your location data for building and studying your individual profile. This profile helps them to have a sneak-peak in your personal life to fabricate a fraud.

Potential Hurdles Limiting The Internet of Things

There is immense hype surrounding Internet of Things (IoT). However, irrespective of technological advancements and immense benefits offered by IoT, there are some potential challenges that limit the application of IoT. In order to understand these hurdles, it is first important to understand what IoT is and how it works?

IoT is a network of interconnected things, devices, machines, animals or humans that are equipped with sensors, software, network connectivity and necessary electronics which enable them to share, exchange and collect data. The sensors of every connection in the network communicate with a cloud system and send data to it through internet connectivity. Once data is received by cloud, the software processes it to take an action like sending an alert or making adjustments to sensor/device with manual efforts of the user.

Following are the hurdles that limit the use of Internet of Things:

  • Availability Of Internet: Although IoT offers high levels of convenience and technological access to users, but there is a basic internet requirement for IoT to be operational. Undoubtedly, internet access is not considered to be a problem by majority of people, but there are still some areas of world where internet connectivity may be spotty or absent.
  • Expenses: IoT requires placement of sensors on the devices or objects. For implementing this technology to its complete potential, there is a requirement to place sensors on roads, traffic lights, utility grids and buildings. Embedding sensors on all required places is looked upon as a huge expense. Progress has been made to develop cheaper sensors. However, more progress is required before organizations would embrace the technology completely.
  • Privacy & Cyber Security: As the number of cyber security breaches is rising, organizations and individuals are thoroughly concerned about the security related to IoT. If every household item or organizational computer is connected over web, it raises the need for strict cyber security protocols.
  • Data Surge: It is estimated that by 2020, around 26 billion items or objects will be a part of IoT. This will lead to the generation of large amount of data. So, businesses need to invest in new hardware, equipment and data mining techniques for effectively collecting and analyzing data in real time.
  • Consumer Awareness: IoT is a technological buzzword, but still 87% of general public is unaware of the term or its actual meaning. There are chances that people may actually be using the technology in some way and yet be unaware of it. This lack of knowledge may result in loss of interest. However, there has been an increased interest in the use of wearable technology which could act as a gateway for other connected objects.

Irrespective of these hurdles, the number of IoT developers is expected to reach 4.5 million by 2020. This gives a hope for new solutions to these hurdles for facilitating the spread of technology and its applications.
