Here's What Nobody Tells You About Application Deployment On Cloud

March 25, 2019

As per IDC, the expenditure of cloud-specific services is expected to grow more than six times by 2020 compared to general IT spending as the adoption rate of cloud-computing systems is increasing. An excellent example of big companies utilizing the power of Cloud is Netflix. Their transition and transformation journey from legacy systems to cloud took about 7 years but the company is reaping benefits now in the form of increased service availability.Enterprises and their business applications are often backed with custom IT systems as they require heavy processing, customized configuration as well as resources. A big downfall of this system is that it requires extra manpower to be employed for managing these systems. But times are changing and so is the functioning of enterprises. Slowly adapting the cloud generation, startups and SMEs are leaning towards moving their existing applications as well as deploying new ones on a reliable cloud server.

Why moving apps directly to Cloud isn’t enough?

Hosting and deploying applications on cloud allows you to reap benefits like direct data sync, increased data accessibility, reduced costs, and redundancy etc. Though enterprises are readily accepting cloud for their upcoming applications, shifting existing apps to Cloud is not easy. Legacy IT systems that form the basis of large business applications are monolithic in nature. According to independent research conducted by Vanson Bourne, 47% companies agree that disparate data systems impact their organization in a negative manner while innovating, developing and reaching to markets with their services and products.They are also configured as per the static capacity of data centers which makes them even more unfavorable for utilizing the dynamic features of Cloud just by simply shifting the existing application. Moreover, in the case of deploying new applications on Cloud, enterprises need to train their overall teams accordingly as they were originally trained to work on traditional IT frameworks.Though application developers understand the dynamics of changing technologies like cloud computing, they might not be aware of the ideal approach that can reap optimum benefits. Here’s a detailed description of all the aspects that need to be kept in mind while choosing a cloud provider for deploying applications on Cloud.

Things to Consider For Deploying Applications on Cloud

The Ideal Platform for App Deployment

Cloud computing offers three models for hosting or deploying applications on a cloud server namely, IaaS (Infrastructure as a service), PaaS (Platform as a service) and SaaS (Software as a service). Depending on your business needs, you can choose the most suitable platform. Considering the usage of businesses, application developers and similar business, Cloud migration makes more sense for most of the established businesses.Cloud migration refers to the process of shifting your current services, data and other business components from on-premise to the cloud. It serves as an ideal choice because it allows you to avoid issues of vendor lock-in as you can always switch from one cloud provider to another based on your needs. As per recent studies more than one-third data will pass through the cloud and therefore, it is better to be prepared than to wait and watch. You should consider cloud migration services for your business as it provides you with the following benefits:

  • Lower costs of infrastructure with the use of cloud
  • Increased business agility
  • Aids in situations of disaster recovery
  • Helps you to be prepared for future needs
  • Allows you to upgrade your current IT systems

Moving Legacy Applications

While moving and deploying data and applications via cloud migration services can turn out to be extremely beneficial for your business; you need to keep a few factors in mind before going ahead with it for your business.

  • Your approach to cloud migration: In order to use cloud migration services effectively for your legacy apps, your first step is to determine how will you be using it for your organization. You need to conduct a software audit and check the status of all your existing applications.  

If the effort of migrating an app is higher than its output value, you can filter it out. You can retire all the redundant applications once you’re done with the audit. Based on this, you can also map different applications and find out the dependencies before the migration process.

  • Syncing development tools with Cloud: The next thing to check here is to consider if your development practices can fit in the cloud environment and if you shift the whole setup, what will be the access control policies for your code documentation. This step needs to be addressed if your development practices are leaned towards in-house development rather than using software tools. If you’ve developed your code using tools, syncing them on Cloud is fairly easy.
  • On-Premise resource integration- Business software often integrate with other applications and resources such as databases for information fetching. When moving performing cloud migration, you need to figure out how these application resources will be accessed. For example, if client applications use a virtual private network to access on-premise elements due to security reasons, you need to check with your cloud service provider to ensure your needs.  
  • Supported development stack- Technology is evolving with growing needs and so are cloud server and migration offerings. Based on your choice of technology stack including languages and databases for your existing application development needs, you need to carefully choose a cloud provider that supports your application stack completely. Shifting your application to Cloud should offer easy and smooth development for your applications.

Selecting a Cloud Service Provider

Whether you need to shift an existing application to cloud or are looking for a cloud solution for deploying new applications, the most important thing to consider is the ideal cloud provider. With the expansion of cloud service providers over the years, the competition has also increased.But this doesn’t mean that the most popular provider could be suitable for your needs. You need to fix your requirements first and then thoroughly evaluate a suitable vendor that could provide you the best cloud server accordingly.

  • The most valuable trait of cloud computing is that it allows you to deploy your application at minimum or low cost throughout the world. When choosing a cloud service provider, you must consider an option that allows you to deploy your application without any scalability issues. This way, your audience can access your application in a fast and easy manner.
  • Another important factor to be aware of is vendor lock-in. Many cloud service providers might seem attractive to you as they provide you with proprietary APIs with built-in code. Choosing a provider based on this option might lead you to end up with vendor lock-in and can become difficult to move your application anywhere else when needed. Therefore, instead of choosing these as an easy go option, you should always stick to the technology stacks that you’ve already worked on and are comfortable with.

Prerequisites

Deploying applications on Cloud seems like an easy option and while it does take a lot of burden off your shoulders, there are a few prerequisites to keep in mind before executing the final step.

  • Figure out the path through which all members of the system including the team and the customers access information. Based on this information, create workflows that make the process easier and more accessible through Cloud.
  • Consider the job responsibilities of your team members and check for the chances of change in their roles due to this shift. You might want to signal the team about this priorly to avoid any end-minute chaos.
  • Deploy your application features through an iterative methodology rather than executing everything at once. This will prevent your users from getting overwhelmed
  • Cloud service providers update their applications according to the market and technology changes. Keeping this in mind, you must prepare your team for change management to avoid any hassle.
  • Test and deploy your application and product updates repeatedly through a designed process.

Conclusion

Deploying applications on Cloud can turn out to be successful for your legacy as well as new applications if you take care of the above-discussed aspects beforehand. These will help you in choosing a cloud service provider that meets all the necessary characteristics.

Image-based 3D Object Reconstruction State-of-the-Art and trends in the Deep Learning Era

3D reconstruction is one of the most complex issues of deep learning systems. There have been multiple types of research in this field, and almost everything has been tried on it — computer vision, computer graphics and machine learning, but to no avail. However, that has resulted in CNN or convolutional neural networks foraying into this field, which has yielded some success.

The Main Objective of the 3D Object Reconstruction

Developing this deep learning technology aims to infer the shape of 3D objects from 2D images. So, to conduct the experiment, you need the following:

  • Highly calibrated cameras that take a photograph of the image from various angles.
  • Large training datasets can predict the geometry of the object whose 3D image reconstruction needs to be done. These datasets can be collected from a database of images, or they can be collected and sampled from a video.

By using the apparatus and datasets, you will be able to proceed with the 3D reconstruction from 2D datasets.

State-of-the-art Technology Used by the Datasets for the Reconstruction of 3D Objects

The technology used for this purpose needs to stick to the following parameters:

  • Input

Training with the help of one or multiple RGB images, where the segmentation of the 3D ground truth needs to be done. It could be one image, multiple images or even a video stream.

The testing will also be done on the same parameters, which will also help to create a uniform, cluttered background, or both.

  • Output

The volumetric output will be done in both high and low resolution, and the surface output will be generated through parameterisation, template deformation and point cloud. Moreover, the direct and intermediate outputs will be calculated this way.

  • Network architecture used

The architecture used in training is 3D-VAE-GAN, which has an encoder and a decoder, with TL-Net and conditional GAN. At the same time, the testing architecture is 3D-VAE, which has an encoder and a decoder.

  • Training used

The degree of supervision used in 2D vs 3D supervision, weak supervision along with loss functions have to be included in this system. The training procedure is adversarial training with joint 2D and 3D embeddings. Also, the network architecture is extremely important for the speed and processing quality of the output images.

  • Practical applications and use cases

Volumetric representations and surface representations can do the reconstruction. Powerful computer systems need to be used for reconstruction.

Given below are some of the places where 3D Object Reconstruction Deep Learning Systems are used:

  • 3D reconstruction technology can be used in the Police Department for drawing the faces of criminals whose images have been procured from a crime site where their faces are not completely revealed.
  • It can be used for re-modelling ruins at ancient architectural sites. The rubble or the debris stubs of structures can be used to recreate the entire building structure and get an idea of how it looked in the past.
  • They can be used in plastic surgery where the organs, face, limbs or any other portion of the body has been damaged and needs to be rebuilt.
  • It can be used in airport security, where concealed shapes can be used for guessing whether a person is armed or is carrying explosives or not.
  • It can also help in completing DNA sequences.

So, if you are planning to implement this technology, then you can rent the required infrastructure from E2E Networks and avoid investing in it. And if you plan to learn more about such topics, then keep a tab on the blog section of the website

A Comprehensive Guide To Deep Q-Learning For Data Science Enthusiasts

For all data science enthusiasts who would love to dig deep, we have composed a write-up about Q-Learning specifically for you all. Deep Q-Learning and Reinforcement learning (RL) are extremely popular these days. These two data science methodologies use Python libraries like TensorFlow 2 and openAI’s Gym environment.

So, read on to know more.

What is Deep Q-Learning?

Deep Q-Learning utilizes the principles of Q-learning, but instead of using the Q-table, it uses the neural network. The algorithm of deep Q-Learning uses the states as input and the optimal Q-value of every action possible as the output. The agent gathers and stores all the previous experiences in the memory of the trained tuple in the following order:

State> Next state> Action> Reward

The neural network training stability increases using a random batch of previous data by using the experience replay. Experience replay also means the previous experiences stocking, and the target network uses it for training and calculation of the Q-network and the predicted Q-Value. This neural network uses openAI Gym, which is provided by taxi-v3 environments.

Now, any understanding of Deep Q-Learning   is incomplete without talking about Reinforcement Learning.

What is Reinforcement Learning?

Reinforcement is a subsection of ML. This part of ML is related to the action in which an environmental agent participates in a reward-based system and uses Reinforcement Learning to maximize the rewards. Reinforcement Learning is a different technique from unsupervised learning or supervised learning because it does not require a supervised input/output pair. The number of corrections is also less, so it is a highly efficient technique.

Now, the understanding of reinforcement learning is incomplete without knowing about Markov Decision Process (MDP). MDP is involved with each state that has been presented in the results of the environment, derived from the state previously there. The information which composes both states is gathered and transferred to the decision process. The task of the chosen agent is to maximize the awards. The MDP optimizes the actions and helps construct the optimal policy.

For developing the MDP, you need to follow the Q-Learning Algorithm, which is an extremely important part of data science and machine learning.

What is Q-Learning Algorithm?

The process of Q-Learning is important for understanding the data from scratch. It involves defining the parameters, choosing the actions from the current state and also choosing the actions from the previous state and then developing a Q-table for maximizing the results or output rewards.

The 4 steps that are involved in Q-Learning:

  1. Initializing parameters – The RL (reinforcement learning) model learns the set of actions that the agent requires in the state, environment and time.
  2. Identifying current state – The model stores the prior records for optimal action definition for maximizing the results. For acting in the present state, the state needs to be identified and perform an action combination for it.
  3. Choosing the optimal action set and gaining the relevant experience – A Q-table is generated from the data with a set of specific states and actions, and the weight of this data is calculated for updating the Q-Table to the following step.
  4. Updating Q-table rewards and next state determination – After the relevant experience is gained and agents start getting environmental records. The reward amplitude helps to present the subsequent step.  

In case the Q-table size is huge, then the generation of the model is a time-consuming process. This situation requires Deep Q-learning.

Hopefully, this write-up has provided an outline of Deep Q-Learning and its related concepts. If you wish to learn more about such topics, then keep a tab on the blog section of the E2E Networks website.
