海外TECH	DEV Community	How to successfully hold a demonstration for an IoT product without any hardware	https://dev.to/daiquiri_team/how-to-successfully-hold-a-demonstration-for-an-iot-product-without-any-hardware-pbm	How to successfully hold a demonstration for an IoT product without any hardwareWhy is this necessary Several teams often work on the product and sometimes one of the teams does not have time to complete its part It was our case we were developing the web and back end parts of the IoT system and the hardware team on the client s side did not meet the deadline At the same time the product owner has already scheduled demonstrations with customers which he would not like to postpone because some meetings can t be scheduled a second time or the impression will be spoiled But we found a way to get out of this situation and meet all the deadlines with little effort About the productOur client s company manufactures smart scales In our collaboration they were trying to optimize the process of controlling the storage of products in the sales halls of supermarkets and the idea of their product was as follows Demonstration processA test shelf had to be installed in one of the supermarkets for a successful demonstration of the system It was also needed so that our team could test all the subsystems that should work with the shelf According to the demonstration plan the client had to show the process of adding a new store and its employees to the system and adding shelves to the selected store Real time shelf data was displayed on a separate dashboard and informative reports on shelf performance could also be created and viewed In case of deviation of temperature or insufficient quantity of goods employees were notified and were able to solve the problem with the shelf Problem solvingWhat ways out of the situation did we have We could do nothing because the responsibility for the failure of the demo was not on our side At the same time delaying the project delivery date is always unpleasant We will send the invoice later there are risks that we will have to rework some tasks later and the team members have already lost the context and are working on the tasks of other projects Even more critical that our client got into an unpleasant situation because without a shelf it was almost impossible to hold a demonstration successfully So yeah we just decided to create a software equivalent of a physical shelf that would do all the same things as a real shelf when finished We started with requirements development because we had to consider many details regarding the work of the shelf First we thought about how customers and employees will interact with the shelf They can accidentally lean on the shelf which can cause the system to get false statistics You can also forget to close the refrigerator door and the temperature will start to rise After working through possible user scenarios we decided that the shelf in this case could be replaced by a separate or not separate application that would be able to easily add a large number of new shelves and send data about the operation of each shelf We immediately informed the client about this idea and that when we do it it will be possible to run a demo using our test application only It will be as relevant as possible to how our admin panel will work with real shelves The work took us a couple of days of teamwork We simulated the possibility of turning off the shelf or losing connection with it with a probability of every minute Also every minute a random amount of goods was taken from the shelf and if the shelf remained less than loaded with a probability of it was filled again The typical storage temperature range of the product was from to degrees Celsius so every minute we increased the temperature with a probability of and when the temperature exceeded the specified range the employee received a notification We also considered the possibility of sending false indicators which the system had to filter and not take into account in the general work statistics With the help of the software shelf our team tested all the necessary subsystems and demonstrated the operation of the product to the client A few days later our client successfully held the demonstration to their customers and fully validated the product hypotheses When the physical shelf was ready after two weeks we added it to the system We ensured that our software counterpart worked similarly to the physical shelf which again emphasized the correctness of the chosen solution to the problem ConclusionWe at Daiquiri Team believe that the development team must be aware of the client s tasks and problems even if they are outside the competence of the developers This is how the team gets enough background to understand the entire client s problem and be able to solve it completely Saying that you can t continue work because third party system components are not ready is not expedient Components can always be replaced with another solution As a developer I truly believe that all developers should care about the end customer of the product at least partly I participated in many projects and I feel it from real life so if you want to work with me on your IoT project or any other projects ーwrite me directly or contact us on the website and we will be glad to discuss and solve your problem	2022-10-17 14:49:45
海外TECH	DEV Community	Reducing Your Cloud Costs: An Operational Optimization Guide	https://dev.to/blink-ops/reducing-your-cloud-costs-an-operational-optimization-guide-3eh6	Reducing Your Cloud Costs An Operational Optimization GuideCloud costs are top of mind as many business leaders and teams are focusing attention on honing their operational efficiency In April at CIO com s Future of Cloud Summit Dave McCarthy research vice president of cloud infrastructure services at IDC shared that cloud spending represents roughly of current IT budgets In the State of Cloud Report by Flexera surveyed executives shared that they estimate they are wasting of their cloud spend while also saying that they expect costs to increase over the next year If you combine those stats there is an efficiency opportunity roughly the size of of IT budgets Achieving those cost savings isn t as easy as flipping a switch There is wasted spend embedded across multiple resource types regions and services By function the main categories of cloud spending are compute time data storage and data transfer In this post we ll outline a framework for reviewing your cloud spending today identifying wasted resources and reviewing your long term infrastructure efficiency Reviewing Your Current Spending“What are we currently spending money on To start you can review your current spend at the account level with the major cloud providers AWS Azure and GCP all have reporting options that enable you to view and filter your spending over a period of time In AWS you can create Cost and Usage Reports In GCP you can review your Cloud Billing Report and view spend by “Project or other filters In the Azure portal you can download usage and charges from the “Cost Management Billing section These views may be useful to get started and see transactional costs such as from data transfers In order to get more granular details on your cloud spending you should leverage resource labels and tags to accurately categorize expenses With labels and tags you can associate resources with specific cost centers projects business units or teams You can then easily organize your resource data create custom reports and run specific queries If you do not currently have a mechanism or standard practice around resource tags and labels you can refer to these how to guides for setting up mandatory tags AWS Enforcing Mandatory Tags Across Your AWS ResourcesGCP Enforcing Labels and Tags Across Your GCP ResourcesAzure Enforcing Mandatory Tags Across Your Azure ResourcesIf you use more than one cloud computing provider you ll need to aggregate invoices and usage reports across vendors In this scenario having consistent tagging methods across platforms is even more useful as it can offer a consistent way to view your resource usage and expenses Once you have a clear sense of your current spending you can look for opportunities to reduce your expenses Eliminating Unnecessary Resources“What resources are we spending money on and not using at all As projects are spun up and shut down there are often resources that become unattached and left behind While they are no longer in use they are still costing your organization money on a recurring basis Ideally you have an automated way to regularly catch and delete these unattached resources With a no code platform like Blink teams can scale up scheduled automations to continuously detect and remove unnecessary resources If you don t have automations already in place you can manually review resources in the console and remove unused ones in bulk It can be time consuming but you may be able to reduce your operating costs significantly this way in the short term To know what types of resources to review here are some common examples Unattached DisksAWS How to Find and Delete Unattached AWS Volumes and GatewaysAzure Finding and Deleting Unattached Disks with the Azure CLIGCP How to Find and Delete Unattached GCP Disks Unattached IP AddressesAWS Finding and Removing Unattached AWS Elastic IP AddressesAzure How to Detect and Remove Unattached Azure Public IP AddressesGCP Finding and Removing Unattached GCP External IP Addresses Old SnapshotsAWS How to Find and Remove Old EBS SnapshotsAzure How to Find and Remove Old Azure SnapshotsGCP How to Find and Remove Old GCP Disk SnapshotsFinding and removing idle resources is a clear way to cut your operating costs but it also is an important practice for maintaining a strong security posture If you leave resources like unattached IP addresses idle NAT Gateways load balancers with no target or orphaned Secrets lying around bad actors could find them and take advantage of the information In this way resource management is key to reducing costs and reducing risk Optimizing and Updating Resources“How can we optimize our existing resources Now that you ve reviewed and removed unused resources you can now look at optimizing the resources you are using Using the Right Family for the JobWhether you are creating new resources or evaluating existing ones it s important to consider which family of resources best fits your needs If you re using general purpose machines there might be another more cost effective machine that is a better fit Depending on your usage you may need more capacity in some specifications than others For example if you re using AWS there are Compute Optimized instances under the C family e g EC Cg instances which offer optimal price performance for especially computing intense use cases like batch processing workloads and scientific modeling Other families include Memory Optimized e g EC Ra instances and Storage Optimized Ec lmgn instances There are lots of other families e g IOPs network accelerator optimized depending on the platform and the specification you want to optimize for When considering your performance requirements you might have use cases like batch jobs or workloads that are fault tolerant Azure GCP and AWS all have unused capacity that they offer as less expensive less reliable Spot VMs Compared to on demand instances they are up to less expensive to run Updating to New MachinesWithin each of these families there are often newer versions being offered Often the newer versions run more efficiently or have higher performance so it s a good best practice to upgrade to newer versions as much as you can One example of this is with EBS volumes By switching from EBS GP volumes to EBS GP volumes you can reduce your costs by There are some small performance tradeoffs but it s important to keep these types of upgrade opportunities in mind Another AWS example is switching from older machines to ones that use the new AWS Graviton processors Instances running on Graviton processors vs Intel processors offer up to better price performance with specific efficiencies varying by family Looking for Low CPU UsageOne way to optimize your spending is by rightsizing resources to match the usage level that you need For example you may be running an instance or virtual machine that has more computer capacity than you need By reviewing your usage data you can determine if you are running at an average CPU usage of or less for example By reducing the size or type of instance you can slightly reduce your spend which adds up over time Here are some how to guides that show examples for each platform AWS Finding and Resizing Amazon EC Instances with Low CPU UsageGCP Finding and Resizing GCP Compute Instances with Low CPU UsageAzure Finding and Resizing Azure Virtual Machines with Low CPU Usage Using Long Term Resourcing for Predictable CPU UsageAnother way to optimize your costs is by leveraging reserved instances or committed use discounts In exchange for predictable computing expectations the major cloud providers offer resources at a discount with a committed term such as year or years Here are some how to guides that show examples for each platform AWS Lowering Costs on Long Running AWS EC InstancesGCP Lower Costs for Long Running GCP Instances with Committed Use DiscountsAzure Optimizing Costs for Long Running Azure VMs with Reserved Instances Starting Nightly Non Production Scale DownsAre there any resources that you can shut down when they are not being used For example if your team is working with a test environment during certain work hours you don t need to run it hours a day You can scale it down at night and scale it back up the next morning With some automation pausing and restarting a non production cluster could be as simple as clicking an approval button in a slack message and reducing your daily cloud costs Here are a couple examples of how to pause and restart clusters nightly AWS How to Scale Down AWS EKS Clusters NightlyGCP How to Pause Your GKE Cluster NightlyAzure How to Pause Your AKS Cluster Nightly Storing and Moving Data Efficiency“Can we optimize how our data is stored and transferred Storing Only Relevant DataYour cloud bill is also impacted by how much data you are storing While it s useful to collect data to see how your services are running it likely becomes less useful and relevant over time Even if you want to maintain as much data as possible you ll want to employ a strategy of periodically switching data over to less costly long term storage vehicles such as Amazon s S Glacier storage Here are some how to guides for AWS on how to identify data that hasn t changed in a while and how to reduce logging storage costs AWS Detecting AWS DynamoDB Tables with Stale DataAWS Lowering AWS CloudTrail Costs by Removing Redundant TrailsAWS Ensuring AWS CloudWatch Log Groups Have Set Retention Periods Optimizing Data TransfersData transfers may also account for a significant part of your cloud costs and vary greatly depending on their source destination method of transport and size You can also likely expect charges if you are transferring data across regions or across availability zones Unless your business case requires it you should look to avoid data transfers that go across regions and availability zones While inbound or ingress data transfers between the internet and your cloud provider are not charged outbound transfers are charged per service You should reduce outbound data transfers from your cloud to external destinations as much as possible If you are transferring data across AWS services for example you should be utilizing private endpoints This way when you are accessing a S bucket from an EC instance you can avoid data transfer charges The same principle applies for transferring data from your cloud to on premises locations and tools like AWS Direct Connect GCP Direct Peering and Azure ExpressRoute which may offer lower cost per GB compared to transfers over the internet Actual savings depends on the amount of data you are moving and if you are below a certain threshold it might not make sense You can read more about the types of data transfer charges in the Cost Optimization pillar of the AWS Well Architected Framework or these AWS GCP and Azure resources Achieving Operational Excellence with Blink AutomationsSo far we have covered several areas where you and your team can focus and optimize your costs but significant savings over time takes new processes Beyond finding unused resources you need an automated process for alerting you to cost reduction opportunities and then making approval for removing resources as easy as clicking a button If you only rely on scripts you may accidentally take down environments or orphaned resources that should have been left up With Blink you can use no code automations to achieve operational excellence In the cost optimization context Blink lets you create and run dozens of common resource checks and send reports to email or Slack channels with simple actionable options By running these Blink automations on a schedule you ll be able to confidently ensure that you are achieving operational excellence not just one time but daily You can take the same Blink automation approach for other operational excellence categories like security operations incident response troubleshooting and
