    \"Read<\/a>Answer<\/strong>: I am Arun Aravamudhan and I lead the product engineering teams for APM (Application Performance Monitoring)<\/a> and EUM (End User Monitoring)<\/a> product lines at eG Innovations. I\u2019ve been in the software industry for 20+ years in various roles including development, architecture and ops across multiple verticals such as banking, e-commerce and telco. I have been an early adopter of APM products since the mid 2000s and my focus has predominantly been on performance tuning and monitoring of large-scale distributed applications.<\/p>\n\n\n\n

    <\/span>Question<\/strong>: What attracted you to eG Innovations and what is your role at eG Innovations?<\/span><\/h3>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

    Answer: <\/strong>eG Innovations offered me the opportunity to take all that I had experienced over the past decades and pour it back into building a great APM product. The company already had a rich heritage in IPM (Infrastructure Performance Monitoring)<\/a> and I saw an opportunity to spearhead the APM feature set.<\/p>\n

    At eG Innovations, my role is to execute on our mission to deliver a world-class APM product that provides tangible business value to our customers. We do that by uniting the application and infrastructure perspectives into a holistic single-pane-of-glass solution for monitoring, diagnosis, alerting, reporting, baselining, capacity planning, and more. We call this a \u201cConverged Application and Infrastructure monitoring<\/a>\u201d solution.<\/p>\n

    My role is very multifaceted in terms of talking to highly technical customers about their needs in a highly dynamic IT environment, converting that into an executable set of specifications for engineers, and balancing multiple factors to prioritize which features to work on vs. which ones to defer.<\/p>\n\n\n\n

    <\/span>Question<\/strong>: What is an APM solution?<\/span><\/h3>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

    \"Application<\/a>Answer<\/strong>: An APM product helps you assess your application\u2019s performance by showing you the end user experience. It allows you to drill down to the business transactions and the underlying infrastructure health. Imagine a user logging on to a system. The request is sent to a firewall, a load balancer, a web server, an app server, and possibly an authentication server or database. The APM system kicks in and tracks all the calls all the way from the browser to the database and back – the entire communication stream. Was there slowness in any step of the logon call chain? Were there errors? Was it due to the browser or the network or the backend? If it was the backend, was it the code or SQL or 3rd party dependencies or even the underlying infrastructure?<\/p>\n

    Essentially, the APM solution shows you how data flows across application tiers using a tag-and-follow mechanism, how much time it spends in each tier, and provides you visibility as for why it behaves the way it does.<\/p>\n\n\n\n

    <\/span>Question<\/strong>: How did APM fit into what eG Innovations was already delivering?<\/span><\/h3>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

    \"eG<\/a>Answer<\/strong>: eG Innovations has been focused on answering the toughest IT performance question of today, which is \u201cwhy is an application slow<\/a><\/em>?\u201d. There is no easy answer to this. Slowness can arise because of issues in the infrastructure \u2013 the server, hardware, cloud platform, storage, database, or infrastructure services like DNS. The eG Enterprise suite from eG Innovations already addressed these aspects of performance monitoring. We realized that problems could also be in the application code itself or in the way the application is querying the database, or in an external service that the application depended on. We realized that APM capabilities were essential if we had to provide reliable answers to the \u201cwhy is my application slow\u201d question.<\/p>\n\n\n\n
