Amazon S3 Glacier vs. Microsoft Exchange

If your organization has a lot of archival data that it needs to be backed up for safekeeping, where it won't be touched except in a dire emergency, Amazon Glacier is perfect. In our case, we had a client that generates many TB of video and photo data at annual events and wanted to retain ALL of it, pre- and post- edit for potential use in a future museum. Using the Snowball device, we were able to move hundreds of TB of existing media data that was previously housed on multiple Thunderbolt drives, external RAIDs, etc, in an organized manner, to Amazon Glacier. Then, we were able to setup CloudBerry Backup on their production computers to continually backup any new media that they generated during their annual events.

You can use Microsoft Exchange Server with peace of mind for e-mail, calendar, communication, scheduling, and collaboration services. Microsoft's Exchange Server is a product designed to provide users with access to the messaging platform from mobile devices, desktops, and web-based systems. Telephony features in Exchange Server support voicemail. Exchange Server successfully offers high availability service with Microsoft Exchange Database availability groups.

• Cheap storage of backup data.
• Can be used as a part of the entire suite of tools from Amazon, without requiring you to leave the familiar stack.

• As we have a large user base of 11,000 users we use MailTips to avoid people getting confused with people with similar names in the organization.
• The integration between Teams Meeting and Resource booking is generally very good. The Scheduling Assistance makes it easy to scan calendars and find free periods to provisionally scheduled events.
• Marking yourself as Out of the Office and busy is easy, as is sharing your calendar within the team/organization or individuals.
• Voicemail integration and the ability to receive missed chats in your inbox are highly used and useful.

• Accessing data stored in Glacier is slow. That shouldn't be a surprise, but it is undesirable nonetheless.
• Retrieving a large amount of data can be expensive; Glacier's intended use is as an archive of rarely-accessed data.
• Some users regard Glacier with fear and uncertainty. Slow retrieval time and high retrieval cost are the greatest risks of using Glacier, and they are also the Glacier interaction that most users have the least experience with.

• The two main factors for the better reliability & Uptime of internally hosted Exchange Server depends on Exchange Server configuration and the level of investment the organization is willing to provide for hosting the Exchange Server On-Premise Environment. As the data is stored in the organization’s hardware, any disaster may lead to the loss of email and servers.
• Losing data might affect business continuity and rebuilding it can be costly.
• Security remains a major concern.
• Security of data loss is main concern. To ensure that, organization needs to configure networks, systems and Exchange platform against possible threats.
• Hardware and license costs are high.

It is the best, and perhaps only, email solution worth considering.

It is difficult to delete the data as you have to wait for inventory and then bucket modification has to expire.

Microsoft Exchange is well suited for inexperienced Messaging Admins and veterans alike. If you have no idea of the fundamentals of modern email (SMTP, mail headers, MX Records, SPF/DKIM, Encryption, etc.) and just need to get people's mailboxes and calendars the support they need, you can use it with confidence. If you are an old pro and want to leverage and dovetail your Powershell and AD with Exchange, you will be rewarded for your efforts.

Exchange is setup with multiple servers behind load balancers to provide high availability.

I would say it's the best email product I've experienced.

We have a good enterprise agreement with Microsoft which affords us quick phone support. I have found the support staff knowledgeable and prompt with a solution when required. At times it may be difficult to schedule a call back, this is mainly due to our need for calls early in the morning which happens to be during a shift change at Microsoft support.

Implementation/conversion can be quite complex and, unless you have certified Exchange administrators in-house, you should strongly consider a 3rd party consultant for this implementation.

Since the rest of our infrastructure is in Amazon AWS, coding for sending data to Glacier just makes sense. The others are great as well, for their specific needs and uses, but having *another* third-party software to manage, be billed for, and learn/utilize can be costly in money and time.

Most of the 365 subscriptions include desktop and cloud versions of Microsoft programs. These "traditional" software may be installed on a desktop computer and used offline without any problems, as long as you have a working Internet connection. Because so many firms still transmit each others file's developed locally using these applications, despite this being an era of cloud computing– there is a strong case for keeping desktop versions available.

The only time Exchange has failed us is when we did something to cause the failure.

Incentivized

• Helped us meet compliance requirements while minimizing costs.
• Simple integration with almost no changes required to our existing S3 management policies.

Incentivized

• It has been an important factor in allowing seamless communication with clients and scheduling business meetings, which in turn works in the company's favor.
• Haven't noticed any negative impact Exchange has had on our ROI. The support team is also responsive and helpful.
