&lt;p&gt;&lt;b&gt;New page&lt;/b&gt;&lt;/p&gt;&lt;div&gt;= AWS Certitifate manager =&lt;br /&gt;
&lt;br /&gt;
This is a internal AWS managed service for SSL and TLS certificates.&lt;br /&gt;
&lt;br /&gt;
One of it&amp;#039;s major drawbacks is limited configuation options.&lt;br /&gt;
&lt;br /&gt;
::If a customer needs a specicifc configuration then it may not work.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
It can create private certificate authaotorites.&lt;br /&gt;
&lt;br /&gt;
ACM also easily intergrates with AWS ELB.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
It&amp;#039;s manin purpose is to simplify certificate use.&lt;br /&gt;
&lt;br /&gt;
::* Easy to add certs.&lt;br /&gt;
&lt;br /&gt;
::* You can use an email address for vertification when adding a cert.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
== Types of Certificate ==&lt;br /&gt;
&lt;br /&gt;
::Public&lt;br /&gt;
&lt;br /&gt;
:::These use a public CA and are trusted by web browsers.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
::Private&lt;br /&gt;
&lt;br /&gt;
:::These are only trusted by devices that are configured to use the privace CA they reference.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
::Wildcard certificates.&lt;br /&gt;
&lt;br /&gt;
:::These simplifiy and save money by allowing *.mycorp.com&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Some you may not know of:&lt;br /&gt;
&lt;br /&gt;
::* Domain validation certficiates &lt;br /&gt;
&lt;br /&gt;
::: Issued based on domain ownership.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
::* Organization Validation certificates &lt;br /&gt;
&lt;br /&gt;
::: A secure certificate that requires the CA to validate the legal name and address.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
::* Extdend Validation cdrtificates&lt;br /&gt;
&lt;br /&gt;
::: Thse have a rigerious vetting to process to validate identity.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
== Securing an S3 website ==&lt;br /&gt;
&lt;br /&gt;
:: Remmeber S3 can only host HTML, JS and CSS - Static only!&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
When you link ACM with an S3 site HTTPS is enabled.&lt;br /&gt;
&lt;br /&gt;
The SSL offloading is done via cloudfront - therefore cloud front is a requirement when enabling HTTPS on S3.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
== With ELB ==&lt;br /&gt;
&lt;br /&gt;
When using with ELB consinder that ELB offloads the SSL.&lt;br /&gt;
&lt;br /&gt;
:* ELB Decripts the message&lt;br /&gt;
&lt;br /&gt;
:* ELB forawrds to the destination&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
== Automation ==&lt;br /&gt;
&lt;br /&gt;
ACM can:&lt;br /&gt;
&lt;br /&gt;
:* Automatically renew certs&lt;br /&gt;
&lt;br /&gt;
:* Send email reminders for manual renewal.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
When you cannot renew:&lt;br /&gt;
&lt;br /&gt;
:* Private certs - issued with the IssueCertfifcate API&lt;br /&gt;
&lt;br /&gt;
:* Imported from external sources.&lt;br /&gt;
&lt;br /&gt;
:* Anything already expired.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
What it works with:&lt;br /&gt;
&lt;br /&gt;
:* AWS services&lt;br /&gt;
&lt;br /&gt;
:: Including EC2&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
== Cases for a Private CA ==&lt;br /&gt;
&lt;br /&gt;
:* Better control&lt;br /&gt;
&lt;br /&gt;
:* Custom policies&lt;br /&gt;
&lt;br /&gt;
:* Better internal resource protection &amp;amp; management&lt;br /&gt;
&lt;br /&gt;
:* Improved incident response&lt;br /&gt;
&lt;br /&gt;
:* Improved auditing&lt;br /&gt;
&lt;br /&gt;
:* Central account management&lt;br /&gt;
&lt;br /&gt;
:* Scalable&lt;/div&gt;</summary>
