Are your applications well architected?

In this workshop, we will explore the best practices on Operational Excellence, Security, Reliability, Performance Efficiency and Cost Optimizations. Think of systems and services that provide business value; Do you know if all of these services are well architected? You will learn how to create mechanisms that are repeatable process to allow improvements over time. At this workshop, together we will explore the best practices using real-world examples to make it more concrete and actionable.

By attending this workshop, software developers and software architects will learn the following:

  • Value proposition and components of Well-Architected applications
  • How to use the Well-Architected Tool to measure workloads
  • Apply the Best practices and Design principles to your applications' self-service framework
  • How to build and deploy faster
  • How to lower the risks
  • Make informed decisions

Resilient architectures are crucial for all cloud implementations. In this talk, we explore different design patterns to make a distributed application more resilient.

As part of this journey, for any process, we need to ask what if something goes wrong? Then, plan a course of action to the process auto heal without any human intervention and how to lower risks by performing canary deployments. Design starts with at first understanding of requirements and performing empathy map and value chain analysis.

Thinking application as stateless for all the API calls makes the system available most of the time requires creating a cache for common distributed data. Next, we examine how to deal with cascading failures, and timeouts scenarios. Applications, as part of auto-healing, need to Detect, Prevent, Recover, Mitigate, Complement so that the service is resilient.

Key takeaways for the audience are as follows:

  • Resiliency is essential for any feature in cloud
  • Understanding the value chain is critical to identify failure points
  • Challenges come in determining if there is a failure and design the system for auto healing
  • The focus should be first to prevent a failure to occur.
  • Identifying key challenges in your company and tools and techniques to auto-heal and provide a sustainable solution

Securing of the web application is an enormous task. In this talk, we will explore how to protect enterprise applications. We will explore different kinds of vulnerabilities and hot to secure your applications properly. Security patterns need to be understood by first wearing the hat of a hacker and then putting the hat as a defender. In this session, we will explore different security patterns and determine how to prevent attacks.

We will be using Kali Linux to understand Ethical hacking techniques using Metasploitable applications. In the end, we will see how OpenVas can help in scanning the vulnerabilities in the application.

In this session, you will learn:

  • Threat Modeling techniques using the Threat modeling tool
  • Reconnaissance to gather information, Google hacking database, Exploit Database
  • Scanning for vulnerabilities using Burp Proxy, FoxyProxy, SSL Scan, OWASP ZAP
  • Exploitation with DOS attacks
  • Risk Analysis

API Gateway is a way to connect Enterprise application in cloud-ready applications. New applications need to design the data model and create public APIs to be consumed by mobile apps, third party apps, and different devices. We will explore best practices, which you must adopt to be cloud ready. Firstly, we will examine how contract first API development is helping enable more extensible and reliable APIs. Next, we will look at We will ask tough questions during this design session. How to provide security? What are best practices to authenticate? When should we version APIs? Should we use HATEOS for developing APIs? How to support internationalization? How to publish and maintain APIs?

We will take deep dive into following areas:

  • RESTful APIs design patterns: Principles for designing APIs, Hypermedia, Entity tags caching, filtering, Partial items, HAL
  • API versioning techniques: URI path, URI parameter, Content Negotiation, Request header
  • API Security: Threats, Protecting APIs, Authentication, API Keys: How they work? SAML, OAuth and JSON Web Tokens
  • API Gateway: Customer Driven contract development
  • API testing: SoapUI, REST-assured

Ever thought that you write code and promote, the application runs and automatically deploys? Do you want to deploy free hosting to your apps? Heroku lets you deploy, run, and manage applications written in open languages and frameworks such as Ruby, Node.js, Java, Python, Clojure, Scala, Go, and PHP. You can quickly deploy your code with a single command using developer tools like git, GitHub, and Docker. We'll build and run your application with our container-based platform, handling compilation, dependencies, assets, and executables so you can focus on creating engaging experiences for your users.

In this talk, we will explore various features of the Heroku Platform, which is a service-based container that manages all the applications.

So we are all the best coders, but have you see the run time of the code you are writing? What is its time complexity? O(n) or O(log n) What can you do to improve the space complexity? In most of the top companies, algorithm and coding problems are critical before you get the face to face interview. The interviewer is looking for how you approach a problem? How you solve the problem? How you optimize the problem?

This talk will not only prepare you for the interviews but will also give confidence on how to crack the coding interview challenges.

In this talk, we will be exploring analytical skills, and coding skills of the top 10 algorithms and common problems asked in interviews. Problem-solving skills are valuable and help develop optimal algorithms. We will look at problem-solving flow charts to make the right decisions for a given problem.

Productivity is key to success in software development. We will be exploring different principles, so you do not have to work for 60 to 80 hours a day? Are you multitasking and nothing is getting done? Do you feel that there are lots of moving parts and nothing is getting accomplished? What can you do to make a difference in your organization? What techniques can you adopt to eliminate distractions? How to solve a given problem more efficiently? These will be some of the questions and challenges we will address in this talk. Developers and Architects are designers, problem solvers, and innovative, creative artists. Software design is an art, which requires both left, and right brains to be active so you can understand what customer needs. Next, we will explore habits and tools to plan, learn, research, organize, teach, develop, mentor and architect.

Do you want to not worry about setting up the Kafka connect and want to create an easy way to collect, process, and analyze real-time stream data? In this talk, we will explore how to get data from the website clickstreams, IOT data streams, database logs, data lakes, data warehouses, financial and heal care transitions, social media feeds, or location-based tracking.

In this talk, developers and architects will get a hands-on understanding of the Producers, Streams, and Consumer designs.

This talk is excellent for:

  • Developers/Architects working on Big Data
  • Developers/Architects working on Business Intelligence
  • DevSecOps users
  • Development and analysis of data

In this talk, we will explore why Spark is the most prominent solution as compared to just Hadoop. We will look at MapReduce and how Spark makes the creation of Big Data algorithms simple and faster. Next, we will explore Spark Context and how Resilient Distributed Dataset (RDD) to help with the establishment of Directed Acyclic Graph (DAG); Transformations using map and filter; Actions using collect, count and reduce. Later we will explore the Spark Cassandra connector. We will look at Spark API and Spark SQL. We will also discuss how DataStax helps give a high level of stability to open source Apache Spark and Apache Cassandra projects. Key takeaways from this talk will be for a developer and architect to understand how Apache Spark and Apache Cassandra helps in implementing enterprise level analytical solutions. It is 100x faster than Hadoop!

Real-time analytics is critical for your application success.

We will start with exploring how analytics world have changed with newer and faster models for processing data. Next, we will look at Apache Cassandra.

Apache Cassandra is one of the best solutions for real-time analytics. It is 100x faster than Hadoop! Big Data applications require a speed of data processing and analysis. We will explore topology with examples for building Spark applications.

In this two part workshop, we will demonstrate Apache Spark applications, which connect into Cassandra. We will explore SparkSQL, Spark Clusters, and distributed datasets. Later we will explore Cassandra data modeling strategies.
