The Cloud

---

Future Topic: Succession strategies

Hosting

VPS hosting: servers in the cloud

• Linode: $20/month (TWC uses this)
• Digital Ocean
• Cloud at cost (don't use this for production)

You get a virtual machine in the sky which you have to administrate.

Shared hosting

• peaceworks.ca
• CCj/Clearline : $20/month for a shared host
• http://www.ixwebhosting.com/hosting-plans : $8/month

Somebody else sets a server up and gives people accounts. They typically take care of disaster recovery.

Typically you don't get root. Sometimes you don't get a shell.

Colocation

Put a server in somebody's rack. You pay for the hardware and the hosting.

Computer in your basement (self-hosting)

You take of everything.

Your ISP has to be happy with you.

Server power is expensive.

Pros/cons

• Be careful what you make public
• Be careful of hopscotch attacks

Hosted Services

Types of Services

• Microsoft services (Office 365)
• Storage (SkyDrive, DropBox, Google Drive)
• Hosted Exchange, Sharepoint, OneDrive
• Hosting antivirus

Considerations

• There have to be ways for people to work offline on planes
  • But even Google Docs can be used offline (via an installer?)

• When the Internet is down Brendan goes home. Why?
  • Email
  • VoIP phones
  • File shares that are not local

• Can you do video editing in the cloud?
  • There is an upper limit to the resolution

• Multiple location and home access is easier

• Who does the backups?
  • There is versioning for documents in Office 365

• Sometimes services you depend upon go down. Then what?
  • Can you transfer your services to other providers easily?
  • LibreOffice is going into the cloud as well
  • Mount as a filesystem and use rsync
  • Google provides a way to do sync as well

• Can sysadmins see the documents of their users when they are on the cloud?
  • What happens when people leave?
  • People use their corporate accounts and access data via their browser

• Logging into multiple companies can be difficult

• Do these services all use cookies for sessions?
  • Cookies
  • Session tokens
  • User data storage
  • Persistent TCP sessions?
  • Endlessly refreshing HTTP sessions? WebSockets

Pros/cons

• Self-hosting is complicated so companies are taking it away (also not as lucrative for the companies)
• What happens if you are offline?
  • Adobe was offline in 2014 and people were locked out (how does this work?)
  • What happens when your apps are just web frontends?
• Will all the IT people be unemployed? Not Brendan!

Antivirus?

• Web browsers check every page to make sure it is not malicious?
• You could put the management consoles in the cloud
• You could have clients send everything up to the cloud to be scanned

User Training/Adoptions

• Do corporations just do this to minimize training costs?
  • You have to train people
  • But what happens when there is a breach?

• How to we improve training and workplace culture?
  • Go to management?
  • Sheet of instructions that staff don't read
  • Monthly staff meetings

• What about intentionally baiting users?
  • Report to your users
  • Go to your users individually and educate them?
  • Reduce user rights?
  • Publicize the people who have done bad things
  • Use peer pressure?

• Passwords
  • Shamir's Secret Sharing System : Multiple people each need to put a password in to unlock things. http://point-at-infinity.org/ssss/
  • Brendan does not allow people to set their own passwords. He gives passwords to people.
  • Is it worth running hashcat or john the ripper on passwords?

• Why do users keep sending attachments by email?
  • People have inertia for new things
  • It is harder to put files in shared storage than to email attachments
  • Sharepoint puts links to files instead of attaching them (for internal emails) (and so does GroupWise document management)

• "Permissions" for cloud resources are hard for users to understand
  • Things that are "public" can be public to the world, not just the organization
