Currently there is a limit of 2. One bill per AWS account. Easy to track charges and allocate costs between linked accounts. Volume pricing discount. Resources across all linked accounts are tallied, and billing is applied collectively to allow bigger discounts. Active Directory Provides single sign on to the AWS console, which authenticates directly off of your Active Directory infrastructure. Uses Secure Assertive Markup Language SAML authentication responses. Behind the scenes, sign Ins use the Assume. Role. With. SAML API to request temporary security credentials and then constructs a sign in URL for the AWS Management Console. Browser will then receive the sign in URL and will be redirected to the console. You always authenticate against AD first, and then are granted security credentials that allow you to log into the AWS console. Best Practices Business Benefits of Cloud Almost 0 upfront infrastructure investment. Just in time Infrastructure. More efficient resource utilization. Usage based costing. Reduced time to market. Technical Benefits of Cloud Automation Scriptable infrastructure. Auto Scaling. Proactive Scaling. More efficient development life cycle. Improved testability. DR and Business Continuity. Overflow the traffic to the cloud. Design for Failure. Rule of thumb Be a pessimist when designing architectures in the cloud. Assume things will fail, always design implement and deploy for automated recovery from failure. Assume your hardware will fail. Assume outages will occur. Assume that some disaster will strike your application. Assume that you will be slammed with more than the expected number of requests per second. Assume that with time your application software will fail too. Decouple your components Think SQSBuild components that do not have tight dependencies on each other so that if one component dies, fails, sleeps, or becomes busy, the other components are built so they can continue to work as if no failure is happening. Build each component as a black box. Service Limits Each service has the default limits defined, to see the official AWS documentation on service limits, check here. Networking VPC Virtual Private Cloud Lets you provision a logically isolated section of the AWS Cloud where you can launch AWS resources in a virtual network that you define. You have complete control over your virtual networking, IP ranges, creation of subnets and configuration of route tables and network gateways. Virtual data center in the cloud. Allowed up to 5 VPCs in each AWS region by default. All subnets in default VPC have an Internet gateway attached. Multiple IGWs can be created, but only a single IGW can be attached to a VPCEach EC2 instance has both a public and private IP address. If you delete the default VPC, the only way to get it back is to submit a support ticket. By default when you create a VPC, a default main routing table automatically gets created as well. Subnets are always mapped to a single AZs. Subnets can not be mapped to multiple AZs1. CIDR block available when provisioning an IP space for a VPCAmazon uses 3 of the available IP addresses in a newly created subnetx. Always subnet network address and is never usablex. Reserved by AWS for the VPC routerx. Reserved by AWS for subnet DNSx. Reserved by AWS for future usex. Always subnet broadcast address and is never usable. Amazon DNSBy default all traffic between subnets is allowed. By default not all subnets have access to the Internet. Either an Internet Gateway or NAT gateway is required for private subnets. You can only have 1 Internet gateway per VPCA security group can stretch across different AZs. You can also create Hardware Virtual Private Network VPN connection between your corporate data center and your VPC and leverage the AWS cloud as an extension of your corporate data center. Network Address Translation NAT Instances When creating a NAT instance, disable SourceDestination checks on the instance or you could encounter issues. NAT instances must be in a public subnet. There must be a route out of the private subnet to the NAT instance in order for it to work. The amount of traffic that NAT instances support depend on the size of the NAT instance. If you are experiencing any sort of bottleneck issues with a NAT instance, then increase the instance size. HA can be achieved by using Auto scaling groups, or multiple subnets in different AZs with a scripted fail over procedure. NAT instances are always behind a security group. Network Address Translation NAT Gateway NAT Gateways scale automatically up to 1. Gbps. There is no need to patch NAT gateways as the AMI is handled by AWSNAT gateways are automatically assigned a public IP address. When a new NAT gateway has been created, remember to update your route table. No need to assign a security group, NAT gateways are not associated with security groups. Preferred in the Enterprise. No need to disable SourceDestination checks. Dahua IPC HDB3. 20. C 1. 08. 0P Mini Dome Review Network Camera Critic. This camera has become so popular that some places have sold out quickly. An outdoor 1. 08. P dome for under 2. The previous Dahua camera I reviewed was bullet style, daynight camera with built in IR illuminators and a varifocal lens. This camera forgoes the bells and whistles in trade for a lower price but retains its good image quality. Main Features. 13 2. Megapixel progressive scan Exmor CMOSH. MJPEG dual stream encoding. P 1. 92. 0 x 1. 08. Micro SD memory. IP6. Rated Outdoor Dome. Powered by Po. ESmartphone apps available. Overall, this is an impressive camera with very good image quality, good low light performance, well organized menus and very small. Its small size does mean the range of motion is not as good as larger domes but still pretty nimble and does feature 3 axis adjustments. I was able to put it on my eave which is at and angle and still maintain a level shot. This is what the web interface looks like when you first log in. Theres options to take a snapshot, manually record, chose a stream and more. Across the top are tabs for Live live viewing, Set configure the camera, Alarm setup alarms and Logout. When you click on the Set tab, it takes you this configuration screen. Motion detection areas are cleverly set by clicking boxes to cover or expose the image. The exposed areas are where you dont want motion detection and can be any shape that you can create using the box grid. The camera does a good job of FTPing motion events to an FTP server. I personally use a Western Digital My Book Live 1. TB that can be found a local stores that sell PC accessories. You give it the IP address of the server, user name and password and the directory. Worked really well even with a few cameras writing to it. This camera does have local storage in the way of a Micro. SD card. Regardless of how you record, youll need the Dahua software thats included to view the video and convert it to a common format you can share. I know converting video is a pain, but camera companies do this so you cant alter the video in its original state so that it can be used in court. If they provided a common format, you would be able to tamper with the video. Now onto the images, how well does this camera perform. I mounted the camera at the front of my garage, under the eave. This camera had the 2. While at that wide of an angle, you can not ID someone across the street, it was very effective as people approached my front gate or driveway. As with my other reviews, click on the images below to see the full size image, straight from the camera. Since this camera does not have built in illuminators and it does not have a removable IR cut filter, you do need white light to get a usable image. This first shot I captured with my front porch lights on and available light from the street light across the street. You get a pretty clear image and keeping a pair of flourescent 1. W bulbs on at night may be less expensive than buying a camera with illuminators and also provides a safer environment at night. When the porch lights went off, so did a lot of the image. Still a lot is visible, but not sure you would be able to identify anyone in this darkness because the street light would actually cause a shadow on the persons face. I uploaded day and night videos to You. Tube. To see them at the full 1. P resolution, you must click on the gear icon and select 1. P resolution and then click on the icon with 4 corners to see the video full screen. The street price for this camera is about 1. Ive seen on a camera this good. The pluses for this camera are Price dont know where else you can get a camera this good for this price. P at 3. 0fps. Sony Exmor sensor has excellent daytime quality and performs well in low light. Smartphone apps everyone wants to access their cameras from smartphones these days. The shortcoming of the camera are You must rely on your reseller for support. No DayNight IR Cut Filter. No built in illuminators. Click here to go to the company web page for the camera.
