    It is well suited due to the below reasons 1. Easy collaboration between teams 2. Strong integration with other applications 3. Centralized documentation among teams and within the organisation 4. Project planning and report sharing 5. Employee onboarding is easier and maintain HR policies very well. Less appropriate in below scenarios When this is being used as a main tool for communication rather than its purpose of collaboration.

    What are the best ways to integrate it with salesforce.com? What are the best ways to target our users with this tool? To segment the users? How can I integrate my ads with your adexchange-what sizes are you looking for in terms of banners, skyscrapers and so on. In this way I can plan my in house ad and those for the exchange to be the same size, to avoid duplication of work.

    Zimbra is great for an email system for a medium or large organization with appropriate IT staffing. The system is easy to use for end-users, and has a fantastic web interface. Unfortunately, it is overly complex, when considering staffing requirements and price, when compared with Office 365 or Google Apps for smaller organizations. For other education customers, it is hard to compete with Microsoft and Google providing their services for "Free" now though

    Pros
    Atlassian
    • Cross product linking - If you use other Atlassian products then Atlassian Confluence is a no-brainer for your source of documentation, knowledge management etc. You can show previews of the linked asset natively E.g. showing a preview of a JIRA ticket in a Atlassian Confluence page.
    • Simple editing - Though the features available may not be super complex right now, this does come with the benefit of making it easy to edit and create documents. Some documentation editors can be overwhelming, Atlassian Confluence is simple and intuitive.
    • Native marketplace - If you want to install add-ons to your Atlassian Confluence space it's really easy. Admins can explore the Atlassian marketplace natively and install them to your instance in a few clicks. You can customise your Atlassian Confluence instance in many different ways using add-ons.

    • OpenX is a system that was designed to scale as is evident in some key design decisions found throughout the platform. The multi-server setup that was chosen at Mail.com allowed for a distributed server architecture which separated the front end web delivery nodes from the backend MySQL Database master which replicated data back to each front end delivery node mysql slave. This eased the ability to horizontally scale as needed due to the ingenious separation of the ad impressions data tables on the delivery nodes which were being collected locally on each ad impression and then processed periodically back to to the master database which replicated the aggregated statistics back to the delivery nodes. The ability to load balance across the front end web delivery nodes, add caching at many different layers, utilize a CDN for the static ad images, implement PHP accelerators, and hit memcached instead of the MySQL master made the OpenX platform a service that was very resilient to failures.
    • The ability to optimize the platform is also something that OpenX does very well. This is evident in many of the config key parameters available. In addition to OpenX specific tunable's, optimizations can be made at many different levels in which the system sits. These include hardware and operating system level optimizations, tcp and networking stack optimizations, web server/php-cgi configurations, and database (MySQL InnoDB) tunable's. There are many different optimization knobs that can be tuned to help scale the application for the best performance possible
    • The documentation was simple, to the point, and well written which led to an easy initial implementation and roll out of a multi-server setup. The installation and upgrade procedures were straight forward even for the complexities of the multi-server setup. I also found the OpenX team to be accessible and even got a chance to meet some of the team at their Up Close and Personal events at Cal Tech in Pasadena. Core developers were on hand to answer technical questions and also made themselves available to us via email and irq channels.
    • The open nature of the OpenX platform allows for flexibility in the choice of web serving platform to use (Apache, nginx, Lighttpd) and also the database management systems (MySQL, PostGreSQL)

    Cons
    Atlassian
    • UI Design is very simplistic and basic could make use of more visually interesting colour choices, layout choices, etc.
    • Under the 'Content' menu, it defaults to having a landing page for all L1 and L2 category pages. Meaning as long as the broader content category has a sub-category, it still creates a separate landing page. In my team's case, this often creates blank pages, as we only fill out the page at the lowest sub-category (L3).
    • Hyperlinks are traditionally shown as blue, however, this results into very monotonously blue pages in cases where a lot of information is being linked.

    • Propagation could be improved; ad units that need to go live immediately could take up to 45 minutes to propagate.
    • Over-complexity can be confusing. There are multiple tiers before assigning ad units per order and it seems unnecessary.
    • Real-time reporting or a status dashboard would be great.

    • Zimbra's mobile application leaves much to be desired; it is its weakest point.
    • This forces the use of third-party applications on smartphones, which only offer a more or less complete integration with the ActiveSync protocol.
    • Zimbra allows for an on-premise scenario, which is not for everyone, especially considering that the trend nowadays is to outsource email; in any case, it also offers this alternative.
    • The cost of Zimbra as a SaaS solution comes too close to that of more widely adopted competing options.
    • Zimbra lacks a robust integrated chat system, which its competitors offer.
    • It lacks AI integration.

    I am confident that Atlassian can come with additional and innovative macros and functions to add value to Confluence. In 6 months, Atlassian transformed a good collaborative tools into a more comprehensive system that can help manage projects and processes, as well as "talk" with other Atlassian products like Jira. We are in fact learning more about Jira to evaluate a possible fit to complement our tool box.

    I no longer work at the company where I was using OpenX, but if I were then I'd certainly stay aboard. Frankly, there are a lot of sunk costs involved with building all of the infrastructure we had put in place, the system was working very well even if reporting was a hassle, and our team was trained on it. Also, I'm not aware of another product that does everything else we'd need it to.

    Atlassian Confluence is a great tool for project management, especially for internal documentation. It has a minimum governance requirement to use its full power. Also, it is a little pricy to unlock its full power as well, so it is not recommended for companies with a low budget in my opinion.

    I was given the system to use as part of setting up a whole new site from scratch in less than 2 months, with a large number of specialty hub pages to run ads on and lots of content I needed to run disease specific ads on. The system was easy for me to learn on the fly in a very compressed time frame. I would have loved more chance to really dig in under the hood to see all that it could do, but given how fast I had to work, I got everything up and running and looking great. And I did it ahead of my launch deadline too. My only reservation might be for people who are not as patient as I am in picking things up, or as hands on. Customer service was great if I needed them, and a quick start guide with the essentials would be ideal for those people.

    The web usability of the solution is adequate, with all functions integrated into a single interface. However, it is important to note that in the desktop environment, it lacks its own application and relies on ActiveSync synchronization with reference solutions like Outlook or Thunderbird. Some features, such as the briefcase, will be excluded. The same happens on smartphones.It is also common for competing solutions to include integrated chat or video call tools, which Zimbra lacks. These shortcomings are among the most frequently requested by users.

    They went above and beyond without ever asking for additional money and we met our launch date and immediately started to meet and even surpass our business goals. Nothing was too much trouble, which really stood out compared to other companies I had and was at that time also working with. Customer service can really make or break any business; if i expect my staff to give good customer service, I expect to get it too, and Open X gave it.

    We chose Atlassian Confluence over SharePoint because it's much more user-friendly and intuitive. Atlassian Confluence makes collaboration and knowledge sharing easier with its simpler interface and better search. While SharePoint can be powerful, it often feels clunky and complex, making it harder for our team to actually use it.

    OpenX is less focused than MoPub and it has a bigger reach as it is not limited to the mobile app. Unlike MoPub that focuses on performance, OpenX comes from the branding world and is pushing into CTV and other areas of the industry more catered to traditional media agencies and not pure ad tech players.

    Zimbra is a significantly cheaper option than one of the Microsoft solutions, such as Exchange. It is able to run in a free environment, as it is in the case of Linux. It offers the advantages of a powerful mail manager, such as indexed searches and the integration of contacts and notes, all in one platform. It is constantly updated and the operation of its connection in mobile equipment is remarkable and very efficient. Additionally, it is able to easily integrate with Outlook solutions with its connector, which brings all the benefits of Zimbra to the user under the interface known as "mail manager." So far, I have been using Zimbra for several years and I have not missed my previous work platforms.

    • OpenX made it easy to manage online advertising. At the time I used the product I was the lead developer in charge of implementing the solution but quickly was put into the role of managing the traffic and training other users. It was really easy for a technical user to become a traffic manager. Getting other users trained and up to speed was very efficient.

    • Zimbra is a cheaper email service than other similar platforms and in my point of view offers better features, that's why the company migrated services to this platform several years ago and without a doubt, it has been the best investment.
    • Zimbra has a more user-friendly interface for employees, this has improved response times to external customers of the company.
    • The implementation of Zimbra in the company motivated the IT engineering department to make improvements in open source to adapt it to the needs of the company.
